STM32F205RB datasheet



The STM32F205RB, STM32F20x family is based on the high-performance ARM Cortex-M3 32-bit RISC core operating at a frequency of up to 120 MHz. The family incorporates high-speed embedded memories (Flash memory up to 1 Mbyte, up to 128 Kbytes of system SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.

The devices also feature an adaptive real-time memory accelerator (ART Accelerator) which allows to achieve a performance equivalent to 0 wait state program execution from Flash memory at a CPU frequency up to 120 MHz. This performance has been validated using the CoreMark benchmark.


1. 4 USARTs and 2 UARTs

2. A USB OTG full-speed with high-speed capability (with the ULPI)

3. A second USB OTG (full-speed)

4. Two CANs

5. An SDIO interface
