STMicroelectronics | STM32F102R4T6A

The STM32 family of 32-bit Flash Microcontrollers is based on the breakthrough ARM Cortex™-M3 core.  The STM32 family benefits from the Cortex-M3 architectural enhancements including the Thumb-2 instruction set to deliver improved performance with better code density, significantly faster response to interrupts, all combined with industry leading power consumption. The STM32 family is built to offer new degrees of freedom to MCU users. It offers a complete 32-bit product range that combines high-performance, real-time, low-power and low-voltage operation, while maintaining full integration and ease of development. Compatibility of pin-assignments, peripherals and software across all STM32 devices is a core technical feature throughout this family of microcontrollers.

STM32F102xx low-density USB access line incorporates the high-performance ARM Cortex™-M3 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (Flash memory of 16 or 32 Kbytes and SRAM of 4 or 6 Kbytes), and an extensive range of enhanced peripherals and I/Os connected to two APB buses. All devices offer standard communication interfaces (one I2C, one SPI, one USB and two USARTs), one 12- bit ADC and two general-purpose 16-bit timers. The STM32F102xx family operates in the –40 to +85 °C temperature range, from a 2.0 to 3.6 V power supply.
