STM32F313xx Description
Doc ID 023636 Rev 1 7/58
2 Description
The STM32F313xx family is based on the high-performance ARM
®
Cortex™-M4 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
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 on STM32F313xx devices),
three USARTs, up to two UARTsand CAN. To achieve audio class accuracy, the I2S
peripherals can be clocked via an external PLL.
The STM32F313xx 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 STM32F313xx family offers devices in three packages ranging from 48 pins to 100 pins.
The set of included peripherals changes with the device chosen.
