STM32F427xx STM32F429xx

Description

The STM32F427xx and STM32F429xx devices are based on the high-performance ARM®

Cortex®-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4

core features a Floating point unit (FPU) single precision which supports all ARM® single-

precision data-processing instructions and data types. It also implements a full set of DSP

instructions and a memory protection unit (MPU) which enhances application security.

The STM32F427xx and STM32F429xx devices incorporate high-speed embedded

memories (Flash memory up to 2 Mbyte, up to 256 kbytes of SRAM), up to 4 Kbytes of

backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two

APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.

All devices offer three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose

16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers.

They also feature standard and advanced communication interfaces.

•

Up to three I2Cs

•

Six SPIs, two I2Ss full duplex. To achieve audio class accuracy, the I2S peripherals can

be clocked via a dedicated internal audio PLL or via an external clock to allow

synchronization.

•

Four USARTs plus four UARTs

•

An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the

ULPI),

•

Two CANs

•

One SAI serial audio interface

•

An SDIO/MMC interface

•

Ethernet and camera interface

•

LCD-TFT display controller

•

Chrom-ART Accelerator™.

Advanced peripherals include an SDIO, a flexible memory control (FMC) interface, a

camera interface for CMOS sensors. Refer to Table 2: STM32F427xx and STM32F429xx

features and peripheral counts for the list of peripherals available on each part number.

The STM32F427xx and STM32F429xx devices operates in the –40 to +105 °C temperature

range from a 1.7 to 3.6 V power supply.

The supply voltage can drop to 1.7 V with the use of an external power supply supervisor

(refer to Section 3.17.2: Internal reset OFF). A comprehensive set of power-saving mode

allows the design of low-power applications.

The STM32F427xx and STM32F429xx devices offer devices in 8 packages ranging from

100 pins to 216 pins. The set of included peripherals changes with the device chosen.
