Product details
Overview
STM32F479BGT6 from STMicroelectronics is a high-performance Arm® Cortex®-M4 MCU with FPU, 180 MHz max clock, 2 MB Flash, 384+4 KB SRAM, integrated Chrom-ART Accelerator™, MIPI DSI host controller (720p@30 Hz), and dual CAN 2.0B interfaces. It serves as the main application processor in industrial HMI systems requiring real-time graphics, camera input, and Ethernet connectivity.
For engineers reviewing the STM32F479BGT6 datasheet, STM32F479BGT6 pinout, STM32F479BGT6 application, or STM32F479BGT6 equivalent, key selection factors include its dual Quad-SPI support for external flash expansion, hardware cryptographic acceleration (AES-128/192/256, SHA-2), and 161 I/Os with 159 5 V-tolerant pins for mixed-voltage system interfacing.
Technical Context
The STM32F479BGT6 integrates an adaptive real-time memory accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 180 MHz, alongside a dedicated 32-bit FMC supporting SDRAM, NOR/NAND, and PSRAM. Its dual-bank Flash architecture permits true read-while-write operation for robust firmware updates.
It features a full-featured graphical subsystem: LCD-TFT controller (XGA resolution), MIPI DSI host (with integrated D-PHY PLL and regulator), and DMA2D (Chrom-ART Accelerator™) for hardware-accelerated 2D composition-reducing CPU load during GUI rendering by offloading bitmap blending and format conversion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance graphics-capable MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F769NIH6 | Same Cortex-M7 core (216 MHz), larger 2 MB Flash, but lacks MIPI DSI host; uses parallel RGB LCD only | Suitable for high-res TFT displays without DSI ecosystem; no native support for modern smartphone-style panels | Select when higher CPU performance is critical and display interface is limited to parallel RGB or LVDS |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz, dual-core option, 2 MB Flash, includes DSI host-but requires external D-PHY and has no integrated DCMI | Supports DSI displays but needs external PHY; camera interface must be implemented via custom FPGA or external bridge IC | Choose for maximum compute throughput and future-proof dual-core capability, accepting added BOM complexity for DSI/DCMI |
Compared with STM32F479BGT6, the STM32F769NIH6 trades DSI integration for higher CPU speed and simpler display routing, while the STM32H743VIT6 delivers double the clock rate and dual-core flexibility at the cost of external PHY dependency and loss of hardware DCMI.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F479BGT6 achieves 180 MHz maximum CPU frequency using its internal voltage regulator and ART Accelerator™, which enables zero-wait-state execution from Flash memory. This requires proper VCAP capacitor placement (2.2 µF per pin) and stable 1.7–3.6 V supply. The core's 225 DMIPS rating is measured under Dhrystone 2.1 benchmark conditions with FPU enabled.
Does the part support hardware JPEG encoding/decoding?
No, the STM32F479BGT6 does not include dedicated JPEG hardware acceleration. Its cryptographic accelerator supports AES, HASH (SHA-1/SHA-2/MD5), HMAC, and TRNG-but not JPEG compression/decompression. Developers implement JPEG in software or use external co-processors; the DCMI and DMA2D assist in pixel data movement and format conversion.
What display interfaces are supported and what are their resolution limits?
The STM32F479BGT6 supports LCD-TFT parallel interface (up to XGA/1024×768) and MIPI DSI host (up to 720p/1280×720 @ 30 Hz). The LTDC controller handles RGB timing and layer composition; the DSI host includes integrated D-PHY compliant with v1.2, supporting 1–2 data lanes and HS clock up to 500 Mbps per lane.
Is the part qualified for automotive applications?
No, the STM32F479BGT6 is specified for industrial temperature range (–40 °C to +85 °C) and is not AEC-Q100 qualified. ST offers automotive-grade variants (e.g., STM32F479xxI) with extended temperature support and additional qualification testing-but this specific LQFP176 variant (BGT6 suffix) is intended for industrial and consumer applications only.
