STMICROELECTRONICS STM32F429ZIT6 ARM Cortex-M4 Microcontroller, 144-pin LQFP

The STMICROELECTRONICS STM32F429ZIT6 is a high-performance member of the STM32F4 Series, built around a 32-bit ARM Cortex-M4 core with a floating-point unit (FPU). This advanced microcontroller is engineered for demanding applications, featuring an ART Accelerator and a Chrom-ART Accelerator to optimise execution from flash memory and enhance graphics performance. Its rich peripheral set includes an FMC (Flexible Memory Controller) with SDRAM and TFT support, making it ideal for user interface applications.

The core integrates a full set of DSP instructions and a Memory Protection Unit (MPU) for enhanced application security. It offers substantial on-chip memory with 2MB of program memory and 256KB of RAM. For analogue and control tasks, it includes three 12-bit ADCs (24 channels), two DACs, a low-power RTC, and a comprehensive timer set including twelve 16-bit timers (two for PWM motor control) and two 32-bit timers.

Connectivity and Interfaces

A wide array of standard and advanced communication interfaces is supported, including CAN, I2C, I2S, SPI, UART, USART, and USB. For display connectivity, it features an LCD parallel interface (8080/6800 modes) and an 8- to 14-bit parallel camera interface capable of speeds up to 54 Mbytes/s. Additional system features include a true random number generator, a CRC calculation unit, and a 96-bit unique ID.

Robust System Features

Designed for reliability in industrial environments, it operates from a 1.8V to 3.6V supply range and can withstand an industrial temperature range from -40°C to +85°C. It includes essential power management features like POR, PDR, PVD, and BOR. The device also offers comprehensive debug capabilities via SWD and JTAG interfaces, along with a Cortex-M4 Trace Macrocell™.

Housed in a 144-pin LQFP surface-mount package, this microcontroller provides 114 I/O pins for maximum design flexibility. It is a cornerstone component for a
