Description
SPBT2563C1, class 1 radio module is highly integrated for easy implementation in embedded applications. Class 1 module enables wireless communication with other Bluetooth enabled devices up to 100 m away. The SPBT2563C1 integrates on a unique FR4 PCB support: BT 2.0 radio, 32.768 kHz and 26 MHz oscillators, Vreg as well as PA function. The antenna has not been included in order to grant a degree of freedom to the user in selecting the most suitable design and placement between external and integrated antenna that could be SMA aerial or a low cost antenna trace designed on PCB. The module is based on the ST Bluetooth Transceiver STLC2500C and can be interfaced by the host processor by means of a UART or SPI line (selectable by a pin) for HCI transport, and PCM for voice. SPBT2563C1 module implements an add-on feature perfectly fitting in systems equipped with host processor capable to manage upper and lower Bluetooth stack layers, including profiles. ST Bluetooth SPBT2563 series is specifically targeting all those applications requiring Bluetooth devices integrating up to HCI level. Conformance testing through Bluetooth qualification program enables a fast time to market after system integration, by ensuring a high degree of compliance and interoperability.

Mechanical dimensions
In order to meet environmental requirements, ST offers these devices in ECOPACK packages. These packages have a Lead-free second level interconnect . The category of second level interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com Figure 2.

Application
SPBT2563C1

8.1
Application
Low-power improvements
In low power modes,due to the oscillators continuously runnig, the module current is roughly 2.5 mA ( measured at pin 12). This current consumption can be drastically improved by switching off the two oscillators during low power phases. This can be done by means of Inhibit function (pin 3) which act directly on the internal power supply regulator ; in this mode the module is no more powered and the current consumption becomes < 1 A instead of 2.5mA.
8.2
Low power clock startup time
Due to 32.768 Khz oscillator stabilization , when the module is powered on or when enabled ( Inhibit from Low to High state) a waiting time of at least 500ms must be observed ( Reset signal could be kept Low for the waiting1 time or given after it).
8.3
PCB layout of the antenna output
The microstrip track connected to the antenna (pin 1) should respect a characteristic impedance of 50 . It should be verified particularly if some variations in the final project: dielectric material, tolerances, layout changes. The RF ground island around the antenna is connected only to G1 and G2 pins of the module. This ground island is isolated from other grounds. The ground plane at lower PCB layer should also be isolated from other grounds. Vias every 5 millimeters should connect together RF ground islands of each layer. Figure 3.
