STMicroelectronics | STM32F103R4H6A

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.

The STM32F103x4 performance line family incorporates the ARM Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, highspeed embedded memories (up to 32 Kb Flash and SRAM up to 6 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to 2 APB buses. All devices offer 2x 12-bit ADCs, 3 general purpose 16-bit timers plus 1 PWM timer, as well as standard and advanced communication interfaces: up to 2 I2Cs and SPIs, 3 USARTs, an USB and a CAN. The STM32F103x4 operates from 2.0 to 3.6V  power supply. It is available in both the –40 to +85 °C temperature range and the –40 to +105 °C
extended temperature range.
