STMicroelectronics STM32F479NGH6

Overview

STM32F479NGH6 from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit MCU with FPU and ART Accelerator™, operating up to 180 MHz (225 DMIPS), featuring 2 MB dual-bank Flash, 384+4 KB SRAM (including 64 KB CCM), integrated Chrom-ART graphical accelerator, MIPI DSI host controller (720p@30 Hz), and hardware crypto engine (AES-256, SHA-2, HMAC). It targets embedded HMI systems requiring real-time graphics, camera interface, and secure connectivity.

For engineers reviewing the STM32F479NGH6 datasheet, STM32F479NGH6 pinout, STM32F479NGH6 application, or STM32F479NGH6 equivalent, key selection criteria include its dual Quad-SPI support for external memory expansion, 10/100 Ethernet MAC with IEEE 1588v2 hardware timestamping, parallel DCMI interface (54 MB/s), and 161 I/Os with 159 5 V-tolerant pins - critical for industrial display and vision edge nodes.

Technical Context

This MCU integrates a tightly coupled architecture where the ART Accelerator™ enables zero-wait-state execution from Flash at 180 MHz, while the Chrom-ART Accelerator™ (DMA2D) offloads 2D graphics composition from the CPU. The dual-bank Flash supports true read-while-write for seamless firmware updates without halting operation.

The peripheral set includes two independent CAN 2.0B controllers, USB OTG HS/FS with dedicated DMA and dual PHYs (on-chip full-speed + ULPI for high-speed), and an FMC supporting SDRAM, PSRAM, NOR/NAND - enabling complex HMI with external frame buffer and boot memory.

FAQ

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

The STM32F479NGH6's LCD-TFT controller (LTDC) supports up to XGA resolution (1024 × 768 pixels) in RGB888 format with programmable pixel clock, horizontal/vertical synchronization, and data enable timing. It includes layer blending, alpha blending, and dithering for enhanced visual quality without external GPU.

Does STM32F479NGH6 support hardware-accelerated JPEG encoding/decoding?

No - the STM32F479NGH6 does not include dedicated JPEG codec hardware. Its Chrom-ART Accelerator™ (DMA2D) supports only 2D graphics operations (memory copy, alpha blending, color format conversion). JPEG processing must be implemented in software or offloaded to an external co-processor.

Can the MIPI DSI interface drive a 1080p display?

No - the MIPI DSI host controller is specified for up to 720p at 30 Hz (1280 × 720). Driving 1080p would exceed its maximum pixel clock and lane bandwidth. For higher resolutions, an external DSI bridge IC or alternative display interface (e.g., LVDS via FMC-connected FPGA) is required.

Is the 4 KB backup SRAM retained during Standby mode with VBAT supplied?

Yes - when VBAT is applied and the backup domain is enabled, the 4 KB backup SRAM retains data during Standby mode, along with the 20 × 32-bit backup registers and RTC. This enables persistent storage of calibration data, event logs, or cryptographic keys across full system power cycles.
