STMicroelectronics STM32F107 Connectivity Line MCUs

STMicroelectronics STM32F107xx Connectivity Line MCUs incorporate the high-performance Arm® Cortex®-M3 32-bit RISC core operating at a 72MHz frequency. It also includes high-speed embedded memories (Flash memory up to 256Kbytes and SRAM up to 64Kbytes) and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer two 12-bit ADCs, four general-purpose 16-bit timers plus a PWM timer, as well as standard and advanced communication interfaces: up to two I²Cs, three SPIs, two I²Ss, five USARTs, a USB OTG FS, and two CANs. Ethernet is available on the STM32F107xx.
