STM32F215RET6 Description

The high-performance ARM? Cortex?-M3 32-bit RISC processor of the STM32F215RET6 operates at a frequency of up to 120 MHz. The family has a wide range of upgraded I/Os and peripherals connected to two APB buses, three AHB buses, and a 32-bit multi-AHB bus matrix, along with high-speed embedded memories (Flash memory up to 1 Mbyte, up to 128 Kbytes of system SRAM, up to 4 Kbytes of backup SRAM).

The devices additionally include an adaptive real-time memory accelerator (ART Accelerator?), which enables program execution from Flash memory with performance similar to zero wait states at CPU frequencies up to 120 MHz. The CoreMark? benchmark has been used to certify this performance.

All of the devices feature two general-purpose 32-bit timers, three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers, and two PWM timers for motor control. a real random number generator (RNG). They also have both conventional and cutting-edge communication interfaces. An SDIO, an improved flexible static memory control (FSMC) interface (for products provided in packages of 100 pins and more), a cryptographic acceleration cell, and a camera interface for CMOS sensors are examples of new sophisticated peripherals.

Standard peripherals are also included with the devices.
