The STM32F103RET6 microcontroller

The STM32F103RET6 microcontroller has 512 KB of Flash, 64 KB RAM, 3x16-channel 12-bit A/D converter, 6x16-bit (IC/OC/PWM) timer, 3xSPI, 2I2S, 2xI2C, 5USART, SDIO, USB, CAN, 51 I/Os in a 64-Pin 10 mm x 10 mm x 1.4 mm LQFP package.

The STM32F103xC, STM32F103xD and STM32F103xE performance line family incorporates the high-performance ARM®Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash memory up to 512 Kbytes and SRAM up to 64 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer three 12-bit ADCs, four general-purpose 16-bit timers plus two PWM timers, as well as standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2Ss, one SDIO, five USARTs, an USB and a CAN.

The STM32F103xx high-density performance line family operates in the –40 to +105 °C temperature range, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications.
