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.
The devices offer up to four fast 12-bit ADCs (5 Msps), up to seven comparators, up to four
operational amplifiers, up to two DAC channels, a low-power RTC, up to five general-
purpose 16-bit timers, one general-purpose 32-bit timer, and two timers dedicated to motor
2
control. They also feature standard and advanced communication interfaces: up to two I Cs,
up to three SPIs (two SPIs are with multiplexed full-duplex I2Ss on
STM32F303xB/STM32F303xC devices), three USARTs, up to two UARTs, CAN and USB.
To achieve audio class accuracy, the I2S peripherals can be clocked via an external PLL.
The STM32F302xx/STM32F303xx family operates in the -40 to +85 °C and -40 to +105 °C
temperature ranges from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving
mode allows the design of low-power applications.
The STM32F302xx/STM32F303xx family offers devices in three packages ranging from 48
pins to 100 pins.
The set of included peripherals changes with the device chosen.
