The 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, two 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.
All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers. a true number random generator (RNG). They also feature standard and advanced communication interfaces. New advanced peripherals include an SDIO, an enhanced flexible static memory control (FSMC) interface (for devices offered in packages of 100 pins and more), and a camera interface for CMOS sensors. The devices also feature standard peripherals.
● Up to three I2Cs
● Three SPIs, two I2Ss. To achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audio PLL or via an external PLL to allow synchronization.
● 4 USARTs and 2 UARTs
● A USB OTG full-speed with high-speed capability (with the ULPI)
● A second USB OTG (full-speed)
● Two CANs
● An SDIO interface
