Multiple application platform based on STR750FV2
Introduction
The system described in this user manual, Multiple application platform based on STR750FV2 - ARM7TDMI-STM 32-Bit MCU, is a development board implementing a very high number of powerful features. Figure 1 below shows the main characteristics of the system which can be connected to other systems through the BSPI (Buffered SPI) connector and the I2C connector. Advanced networking is also allowed by the new ZigBee connector for radio link communication at 2.4 GHz. Standard serial connectivity can be established using the CAN connector (both 250 Kbps and 1 Mbps as maximum bus speed are supported), the UART connector (linked to the peripheral UART1 of the STR750FV2) and the mini-USB connector useful for data communication with a PC as well as supplying the system. Another important feature is the 34-pin standard motor control connector and the possibility to switch between four different power sources. Two on-board sensors are also available (inertial sensor and analog temperature sensor) in order to start with a wide application range. Figure 1.

List of features
The STR750-MAP is a system designed for a wide spectrum of high-end applications. Appreciable and innovative features are the new 12-pin socket for ZigBee modules and the possibility to choose among four different power sources. The board mounts the STR750FV2 microcontroller in LQFP100, 14x14 mm package. The pin-out of the STR750FV2 microcontroller is available to the users and placed around the microcontroller itself. The list of features of the STR750-MAP board is as follows:

4.1
Hardware configuration and functionality
Power source selector
The STR750-MAP evaluation board is provided with a power source selector that allows the user to choose between four different ways to power the board including the possibility to recharge the external battery pack while the board is powered through the standard power 9 Vdc power supply or the mini-USB connector.
5/33
Hardware configuration and functionality
UM0442
The configuration of the power source selector as appears in the silkscreen (consider the following abbreviations as a legend for the picture below) is as follows:
BAT: the battery pack is selected as power source. To do this, close the related jumper and connect the battery pack by plugging in its connector as appropriate (see Section 4.2: Battery pack power source). EXT: the external 5 V power source is selected as power source. USB: plug in this jumper once the board is connected to a computer through the mini-USB connector in the upper side of the board. PWR: the standard 9 Vdc power connector is chosen and a voltage regulator (L7805AB) provides the 5 V supply to all the components in the board. Power source selector and jumper legend
Figure 3.
It is strongly recommended to not select more than one power source at a time. This is to prevent possible power source failures, with the consequence to propagate these failures to the board components.
4.2
Battery pack power source
The battery pack is selected by closing the appropriate jumper as shown in the previous section. In order to supply the STR750-MAP the following two steps are required:
Plug the battery pack connector onto the STR750-MAP, using the 2-pin connector named BATTERY in the board silkscreen. Configure the 3-pin strip-line selector S7 as follows: close the middle point of the S7 selector with the point 3 (left side of the S7). In this way, the battery pack is linked to the L6920D step-up converter in order to furnish the right voltage to all the components (see Figure 4). The selector S7 allows the STR750-MAP to be supplied from the battery pack
Figure 4.
As an alert feature, an LED is placed to give a warning if a low battery level occurs (LED D10). The two types of batteries that can be connected to the board to allow all features are the graphite anode single cell Li-Ion or Li-Polymer. The low threshold voltage detector is fixed at 2.7 V (considering the use of a battery pack at typically 3.7 V/1360 mAh).

UM0442
Hardware configuration and functionality When another power source (USB, 9 Vdc) is selected, it is possible to recharge the battery pack. The L6924D battery charger system performs this task.
4.2.1
How to charge the battery pack
It is possible to charge a battery pack connected to the STR750-MAP while the board is powered through the power supply or the USB connector. Although the first method is outlined, the procedure to implement the charge phase is the same for both ways. First of all, the STR750-MAP needs to be supplied. For example, plug in the 9÷12 Vdc power supply connector (closing the appropriate jumper). As a second step, connect the battery pack to the connector, without closing the correspondent jumper in the power source selector. To set up the recharging process, follow these steps: 1. 2. 3. Close the selector S7 in the position 1-2: this is to connect the battery to the recharging circuit. Close the selector S8 in the position 2-3: this is in order to select 5 V standard power source. Close the selector S9 in the position 1-2: by doing this, the L6920 and its circuitry is switched off in order to save power. Selectors configuration to recharge the battery pack
Figure 5.
4.3
External 5 V power sourcer
It is possible to plug in an external 5 V power source by closing the jumper EXT in the power source selector. This feature makes the STR750-MAP highly versatile. Since this power source has no specific connectors, the only way to furnish 5 V to the STR750-MAP, comes directly from the STR750FV2 pin-out placed around the microcontroller itself. In this way, the user can make his own interface board or connect it directly to the microcontroller's pins. Take care to follow these simple steps: the external 5 V can operate only if the EXT (see Figure 3) jumper is closed. After this, the 26th pin of the connectors J1, J2, J3 and J4 placed around the microcontroller (see the following Figure 6), is available to receive the external supply. Pay attention when connecting boards outputting 600 mA as maximum current in order to preserve the STR750-MAP functionalities from damage.

4.4
Mini-USB connector power source
In order to use the mini-USB connector as power source, close the related jumper as described in Section 4.1: Power source selector on page 5 (be sure that the other jumpers are open) and then plug the mini-USB cable onto the connector. This feature can have an impact on the battery charge capabilities of the STR750-MAP as described in Section 4.2. The USB unit integrates a 48 MHz clock for data management and a USBLC6-2P6 application specific device for very low capacitance ESD protection circuit (see the schematics in Figure 23).
4.5
Standard power supply connector
The standard power supply connector is named as PWR in the board silkscreen and, once closed, the STR750-MAP is powered using both laboratory equipment and a common 9÷12 Vdc power supply source. This power source also impacts the battery charge capabilities of the board.
4.6
Memory boot
The STR750-MAP evaluation board allows the user to run the STR750FV2 choosing between 4 memory modes in order to perform the boot phase. To make the appropriate choice for your application, refer to the boot table printed onto the board silkscreen. This table is given here with the associated selectors (see Table 1). SW1 corresponds to Boot1/CS2 in the schematics, on the right side (boundary part of the board). SW2 corresponds to Boot0 pin in the microcontroller and in the schematics (refer to the related schematics in Figure 22).

UM0442
Hardware configuration and functionality Following the STR750FV2 datasheet, the boot table given in Table 1 and Figure 7 could be useful to clarify the layout. Table 1. Boot table
Memory model FLASH SRAM MEM SMI SW2 - SW1 00 01 10 1-1
In Table 1 above, the "0-0" configuration corresponds to the boot from the embedded FLASH memory sector "B0F0" mapped at 0h. The configuration "0-1" corresponds to the embedded SRAM mapped at 0h. The configuration "1-0" corresponds to the boot from the system memory mapped at 0h. Finally the configuration "1-1" corresponds to the boot from external SMI bank 0 mapped at 0h. Figure 7. Memory boot selectors and example of configuration
The configuration chosen here corresponds to the MEM memory model.
4.7
STR750FV2 pin-out
To enhance debugging features as well as the possibility to easily connect a secondary board, the whole pin-out of the microcontroller is available to the users and located around the microcontroller. The pin-out is arranged around the microcontroller with 4 connectors placed one per side. Since the LQFP100 package is used, each connector is composed of 26 pins with the last pin as a spare for the STR750FV2 pin-out. The 26th of each connector is used as 5 V external power source when the jumper EXT in the power source selector is closed (see Section 4.3 for details). To facilitate the use of this pin-out, the pin correspondence is printed close to each connector. Table 2 and Figure 8 show the numbering for the connector related to pin 1 to 25 (connector JE1 in the layout). The same numbering is used for the other connectors, where the last pin is connected for the external 5 V supply. Table 2 describes the connector/pin-out association.

The motor control connector
The STR750FV2 is an MCU suited for Motor Control applications since it embeds timers which can be used for dead time generation and edge/center aligned waveform emergency stop. This feature makes it ideal for induction and brushless DC motor control. The STR750-MAP is provided with a 34-pin fully featured connector (J11 in the board layout) dedicated to these kinds of applications. Table 3 below lists the association between each connector pin and the related functionality and microcontroller pin correspondence. Table 3. Motor control connector and STR750FV2 pins correspondence

In applications where the 5 V supply comes from the motor control connector, all the jumpers of the power selector must be open. Of course, if the 5 V is furnished from the STR750-MAP to the MC, choose the appropriate supply from the power supply selector by closing the corresponding source. Pay particular attention also when using jumper J15. It allows the user to provide 3.3 V to the MC connector, when it is closed (jumper J15 is open by default). In any case, 3.3 V cannot be supplied by the motor control connector. Figure 9. 34-pin motor control connector

Mini-USB connector
The mini-USB connector provides both data management features as well as board supply operations (board supply and battery pack recharge), see Figure 10 and Table 4. Figure 10. Standard Mini-USB connector
Table 4.
Pins and signals correspondence for the Mini-USB connector
Name VBus DD+ ID GND Colour Red White Green Black Notes Power Data Data + Type A GND/Type B - NC Ground
Pin number 1 2 3 4 5
This standard connector is defined as part of the USB-OTG (USB On The Go) enhancement. It features a single connector type (A or B) and peer-to-peer operations. The configuration present on the STR750-MAP is Type B, as pin 4 is not connected (NC in the table). The USB-OTG is a supplement to the USB 2.0 (or USB 1.0) specifications that allow USB devices to have more flexibility in managing USB connections. As known, the standard USB (USB 1.1/2.0) uses Master/Slave architecture. A USB host acts as a Master and a USB peripheral (aka USB Device) acts as a Slave. Only the USB host can schedule the configuration and data transfers over the link, while the USB peripherals cannot initiate data transfers. They only respond to instructions given by a Host. The USB-OTG compatible devices are able to initiate the session, control the connection and exchange Host/Peripheral roles between each other. With this new architecture, two new protocols are introduced: SRP (Session Request Protocol) and HNP (Host Negotiation Protocol). Two new classes of devices are defined: OTG A-device and OTG B-device. This terminology defines which side supplies power (VBUS) to the link. The OTG A-device is a supplier and an OTG B-device (our case) is a consumer. The default link configuration is that A-device is Host and B-device is a Peripheral (this may be reversed later by using HNP). These devices are fully backward compliant with USB 1.1/2.0 and behave as standard USB Hosts or Peripherals when connected to standard (no OTG) USB devices.
12/33
UM0442
Hardware configuration and functionality The USB-OTG standard defines only one-to-one connection. Contrary to the standard USB there are no USB Hubs defined by the USB-OTG. Connecting the USB hub between two OTG devices leads to losing all USB-OTG capabilities.
4.10
JTAG connector
To allow enabling of debug features as well as programming capabilities, the STR750-MAP is equipped with a standard JTAG connector. Figure 11 below shows how the pins and the corresponding signals are placed in the JTAG connector. Figure 11. The JTAG connector
4.11
On-board sensors
As described in the features list of the board, the STR750-MAP is provided with one 3-axis digital MEMS accelerometer (the LIS3LV02DQ) and one analog temperature sensor (the STLM20). Both sensors are mounted with their package size (QFN28 and UDFN4 package respectively). While the temperature sensor provides only the analog output (connected to the ADC channel 0, pin number 2 in the microcontroller pin-out), the accelerometer could output both I2C and SPI digital serial output. As a design choice, the STR750-MAP allows the on-board accelerometer to communicate with the STR750FV2 using only the I2C serial bus (the CS pin is fixed at 3.3 V). The board offers the possibility to disconnect this I2C bus from the accelerometer, allowing the microcontroller to communicate with external peripherals using this bus at 3.3 V as Vcc with both standard and fast protocol variants. To manage these settings, refer to Section 4.16: I2C and BSPI connectors on page 18 . The packages are described in Figure 12, where on the left side is the QFN28 package of the accelerometer, and on the right side is the UDFN4 package of the temperature sensor. Refer to the device datasheet in the Reference section for further details.

The ZigBee connector
The ZigBee connector is designed as two adjacent female connectors, each composed of six pins. It is made to host the ZigBee module based on SN260 and adapter in the STR750-MAP. This socket allows the access to the EZSP (Ember Zetanet Serial Protocol). To localize the connector position inside the board, see the board architecture in Section 3: List of features on page 5. The socket description is defined as follows: Table 5 and Table 6 show the pin-out of the connector (ZigBee module interface connectors J8 and J9), while Table 7 illustrates pin functionality. By means of the ZigBee connector, the EZSP may be accessed through the SPI protocol. Table 5 and Table 6 show the connectors J8 and J9. Table 5. Connector J8 of the ZigBee socket

1. With respect to the ZigBee module based on SN260 with adapter
The HOST_INT signal is at 3.3 V pull-up through a 4.7 k resistor (R49) in series with a 0 resistor (R50). In this way the HOST_INT does not bounce in an unknown state if the SN260 is in reset. In each case the pull-up can be excluded by unsoldering the R50 resistor.

Graphic LCD strip-line connector
A standard 20-pin strip-line is dedicated to the control of a graphic 128x64 LCD. The board is designed to host the LCD in the applications where it is needed, with the possibility to remove it when unnecessary, in order to save power. Table 8 gives pin correspondence and Figure 13 shows pin arrangement and organization. Table 8. LCD socket pin description

CAN connector
The board is equipped with a standard DB9 male connector to enhance networking capabilities, especially in industrial and factory automation environments. The physical layer of the CAN protocol is implemented through the L9616 transceiver. It allows the peripheral to reach standard communication speeds (up to 250 Kbps and up to 1 Mbps) which can be done by setting the selector S5 (located close to the CAN connector, see Figure 2) as appropriate. Taking the middle point of this selector as a reference, and closing this one with pin number 3 (0 in the board silkscreen), the device runs at 1 Mbps as maximum speed. Closing the middle point of S5 with pin number 1 in the layout (1 in the board silkscreen), the communication speed is limited to 250 Kbps. Independently of the speed you select, you must close jumper JP12 to connect the termination resistor, in order to close the communication line on the STR750FV2 side. Jumpers JP10 and JP11 also must be closed to allow communication. They connect the Tx and Rx pins of the transceiver with pins 64 and 63 of the microcontroller respectively, linking the peripheral to the physical layer of the communication protocol.

UART connector
Other networking capabilities are offered by the UART connector on the board. It is linked to the UART1 peripheral of the microcontroller through a ST202EC transceiver, using pins 11, 16 and 17 of the microcontroller itself, respectively for RTS, Tx and Rx capabilities. The jumper JP19 near the transceiver, once closed, enables the CTS functionality. If open the corresponding shared pin of the microcontroller (pin 15) can be used by the EXT connector. Before having a look at the pin correspondence Table 10 (the connector is a DB9 male as the one used for CAN), a brief description of the S6 selector is needed. If you close between the middle point and point 1 (upper side, near the connector), you enable the RTS functionality, at the same time the jumper JP13 must be closed. Elsewhere, if you close the middle pin with pin 3 you enable the NULL Modem mode (at the same time jumper JP13 must be opened).

I2C and BSPI connectors
Both the I2C and BSPI connectors are shared with other devices placed on the board, but they are useful in order to allow on-system communication capabilities for the STR750-MAP. The I2C peripheral bus of the microcontroller shares the pin between the 3-axis accelerometer and the connector for external devices. Star ting from the microcontroller pin out, pins 29 and 30, SDA and SCL respectively, are connected to the middle points of two 3-pin strip-line selectors, S2 and S1 respectively. If both these selectors are closed between the middle point and the point 3, we connect the microcontroller to the I2C bus of the accelerometer sensor. If we close between their middle point and point 1, the microcontroller is connected to the external I2C connector, allowing communication with an external device respecting the I2C standard protocol specifications. The left diagram in Figure 16 shows the configuration to select the accelerometer on the I2C bus. The diagram on the right is extracted from the schematic.

Figure 17. The I2C bus schematic
In order to allow capabilities such as system interconnectivity, the BSPI (Buffered SPI) connector is available to the users. It is located adjacent to the mini-USB connector (see Figure 2 for the component placement) and the pin correspondance is described in the related schematics (see Figure 22).

ADC connector and potentiometer
The STR750-MAP offers the possibility to connect analog devices and/or signal generators, directly to the ADC peripheral by using a 4-input ADC connector. These input channels are provided with a RC filter with parameters calculated using the lowest conversion time allowed by the STR750FV2: 3.75 s. Figure 18 shows the schematic of the connector and the corresponding pin-out.

The ADC peripheral channels used for this connector are: 2, 13, 14 and 15, connected to pins P0.12, P1.12, P1.13 and P1.14 respectively. The dedicated potentiometer (useful to test the peripheral features) is also present in the STR750-MAP layout adjacent to the connector. It is attached to the ADC channel 12 (pin P1.11): see Figure 19 below. Figure 19. The ADC potentiometer schematic

User LEDs and push buttons
As well as the ADC connector and potentiometer, debugging and testing capabilities of the user specific applications are also supported by 6 on-board user LEDs and 2 push buttons. Each LED is accessible by connecting the correspondent jumper which is to minimize the load effects on the other peripherals that use the same pin-out (i.e. the user LEDs attached to pins P0.22 and P0.23 share this port with the UART connector circuit). These jumpers are given in Figure 20 and are also illustrated in the board silkscreen. Figure 20. User LEDs schematic
