2 Description
The STM32F303xB/STM32F303xC family is based on the high-performance Arm
®
Cortex
®
-
M4
32-bit RISC core with FPU 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 40
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), seven comparators, 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 control. They
also feature standard and advanced communication interfaces: up to two I
2
Cs, up to three
SPIs (two SPIs are with multiplexed full-duplex I2Ss), 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 STM32F303xB/STM32F303xC 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 STM32F303xB/STM32F303xC family offers devices in four packages ranging from
48
pins to 100 pins.
The set of included peripherals changes with the device chosen.
