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® singleprecision
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.

These features make the STM32F427xx and STM32F429xx microcontrollers suitable for a
wide range of applications:
• Motor drive and application control
• Medical equipment
• Industrial applications: PLC, inverters, circuit breakers
• Printers, and scanners
• Alarm systems, video intercom, and HVAC
• Home audio appliances
