STMicroelectronics STM32F429ZGT6TR

Overview

STM32F429ZGT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 180 MHz (225 DMIPS), featuring 1 MB flash, 256+4 KB SRAM (including 64 KB CCM), integrated LCD-TFT controller supporting up to 4096×2048 resolution at 83 MHz pixel clock, and Chrom-ART Accelerator™ for hardware-accelerated 2D graphics. It targets high-resolution embedded HMI systems requiring real-time display control, camera interface (DCMI), and Ethernet connectivity.

For engineers reviewing the STM32F429ZGT6TR datasheet, STM32F429ZGT6TR pinout, STM32F429ZGT6TR application, or STM32F429ZGT6TR equivalent, key selection criteria include LCD-TFT controller capability, dual CAN 2.0B support, USB OTG HS/FS with dedicated DMA, 10/100 Ethernet MAC with IEEE 1588v2 hardware support, and 168 I/Os with 90 MHz toggle rate and 5 V tolerance on 166 pins.

Technical Context

This MCU integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from flash memory, and a dedicated LCD-TFT controller (LTDC) with full programmability - not available on STM32F427xx variants. Its dual USB OTG controllers include one high-speed (HS) with ULPI interface and dedicated DMA, plus full-speed (FS) with on-chip PHY.

The device features a multi-AHB bus matrix, 16-stream general-purpose DMA with FIFOs, and a flexible memory controller (FMC) supporting SDRAM, NOR/NAND, and PSRAM. It includes two 12-bit DACs, three 12-bit ADCs (up to 7.2 MSPS in triple interleaved mode), and a true random number generator (RNG).

FAQ

What is the maximum resolution supported by the integrated LCD-TFT controller?

The LTDC supports total display dimensions up to 4096 pixels wide and 2048 lines tall, with pixel clock frequencies up to 83 MHz. This enables native support for WUXGA (1920×1200) at 60 Hz or QXGA (2048×1536) at lower refresh rates, depending on interface timing constraints and external memory bandwidth.

Does STM32F429ZGT6TR support USB High-Speed device mode?

No - the USB OTG HS peripheral operates only in host or OTG mode with external ULPI PHY; it does not support high-speed device mode. The integrated FS PHY supports full-speed device, host, and OTG roles, while HS functionality requires external ULPI transceiver for host/OTG use cases.

How many independent CAN interfaces does this MCU provide?

STM32F429ZGT6TR integrates two fully independent bxCAN 2.0B controllers, each with its own message RAM, filter banks, and dedicated APB bus interface. Both support standard and extended identifiers, loopback self-test, and automatic retransmission - enabling dual-bus automotive or industrial network nodes.

Is the Chrom-ART Accelerator™ compatible with external SDRAM frame buffers?

Yes - the Chrom-ART Accelerator™ (DMA2D) can read source data and write destination data directly to external SDRAM via the FMC interface. This allows efficient composition of UI layers stored in SDRAM without burdening the CPU or consuming internal SRAM bandwidth.
