Description

The STM32F302xx/STM32F303xx family is based on the high-performance ARM? Cortex?-M4F 32-bit RISC core operating at a frequency of up to 72 MHz, and embedding a floating point unit (FPU), a memory protection unit (MPU) and an embedded trace macrocell (ETM). The family incorporates high-speed embedded memories (up to 256 Kbytes of Flash memory, up to 48 Kbytes of SRAM) and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
