The STM32 connectivity line is new STM32 line from ST.
It is 32-bit microcontroller with USB OTG, Ethernet with IEEE 1588, dual CAN, audio class I²S.
The STM32 connectivity line is intended for applications where connectivity and real-time performance are required: industrial control, control panels for security applications, UPS, car home.
The family includes devices with 64 to 256 Kbytes of on-chip Flash memory, up to 64 Kbytes of SRAM, and 14 communiation interfaces. LQF64, LQFP100 and BGA100 packages are available.
10/100 Ethernet MAC with embedded DMA and IEEE 1588 hardware support
Economical networking and accurate clock synchronization
Ethernet PHY connectable using MII and RMII interfaces
Full flexibility in the PHY selection
USB 2.0 On-The-Go (OTG) full speed with embedded OTG PHY
USB host capability, no need for an external USB OTG controller or PHY
Dual CAN 2.0B active
Gateway capability with connectivity to 2 independent CAN buses and twice more filtering capabitily in single CAN mode
Dedicated buffers for USB OTG and dual CAN peripherals
Simultaneous usage of USB and CAN, allowing gateway implementation
PLL block offering advanced clock schemes to core and peripherals
Flexibility and optimal cost for clocking simultaneously USB, CAN, Ethernet MAC, Ethernet PHY and audio class I²S
Support for Ethernet, USB, CAN, SPI, I²C, UART/IrDA, 10 timers, and up to 80 5 V-tolerant GPIOs; analog capability with 2x 12-bit ADCs, 2x 12-bit DACs and full supervisor functions
Because all these peripherals can work simultaneously, the STM32 Connectivity line is a great communication gateway
Flexible bootloader supporting USART, CAN and USB device firmware upgrade (DFU) class
Flexibility of communication interface
Security as the bootloader cannot be erased, so guaranteeing that a new code can always be reprogrammed
Flexible power and clock management with multiple low-power modes, and a low-power real-time clock (1.4 μA typ at 3.3 V) with programmable wake-up features, 84 bytes for data backup
Tailor your system on the fly to balance performance and power consumption as needed - even in standby mode, the RTC can be kept running on battery while saving key application data in the 84-byte backup
STMicroelectronics offers a full range of development and
programming tools for the STM32 family, designed to deliver a competitive
advantage in terms of productivity and time-to-market. STM32
