STM32F103RET6

STM32F103RET6 Description

The STM32F103RET6 from the STM32F103xC, STM32F103xD, and STM32F103xE performance line family includes a high-performance ARM Cortex -M3 32-bit RISC core operating at 72 MHz, high-speed embedded memories (Flash memory up to 512 Kbytes and SRAM up to 64 Kbytes), and a wide range of enhanced I/Os and peripherals connected to two APB buses. All devices have three 12-bit ADCs, four general-purpose 16-bit timers, and two PWM timers, as well as standard and sophisticated communication interfaces, including up to two I2Cs, three SPIs, and two I2Ss, one SDIO, five USARTs, a USB, and a CAN.
