The STM32F429XX devices is 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 STM32F429xx devices incorporates 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.
a true random number generator (RNG). They also feature standard and advanced
communication interfaces.

Advanced peripherals include an SDIO, a flexible memory control (FMC) interface, a
camera interface for CMOS sensors. Refer to Table 2: STM32F429xx features and
peripheral counts for the list of peripherals available on each part number.
The STM32F429xx devices operates in the –40 to +105 °C temperature range from a 1.8 to
3.6 V power supply.
The supply voltage can drop to 1.7 V when the device operates in the 0 to 70 °C
temperature range 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.
