Product overview

Description

The STM32F303x6/8 family incorporates the high-performance Arm® Cortex®-M4 32-bit RISC core operating at up to 72 MHz frequency embedding a floating point unit (FPU), high-speed embedded memories (up to 64 Kbytes of Flash memory, 12 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The STM32F303x6/8 microcontrollers offer up to two fast 12-bit ADCs (5 Msps), up to three ultra-fast comparators, an operational amplifier, three DAC channels, a low-power RTC, one general-purpose 32-bit timer, one timer dedicated to motor control, and four general-purpose 16-bit timers. They also feature standard and advanced communication interfaces: one I2C, one SPI, up to three USARTs and one CAN.

The STM32F303x6/8 family operates in the –40 to +85 °C and –40 to +105 °C temperature ranges from 2.0 to 3.6 V power supply. A comprehensive set of power-saving modes allow the design of low-power applications.

The STM32F303x6/8 family offers devices in 32 and 64-pin packages.

Depending on the device chosen, different sets of peripherals are included.
