STMicroelectronics STM32F479NIH6

Overview

STM32F479NIH6 from STMicroelectronics is a high-performance Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 180 MHz (225 DMIPS), featuring 2 MB flash (dual-bank), 384+4 KB SRAM (including 64 KB CCM), integrated Chrom-ART Accelerator™ for GUI rendering, MIPI DSI host controller (720p@30 Hz), and dual CAN 2.0B interfaces - deployed in industrial HMI systems requiring real-time graphics, camera input, and deterministic connectivity.

For engineers reviewing the STM32F479NIH6 datasheet, STM32F479NIH6 pinout, STM32F479NIH6 application, or STM32F479NIH6 equivalent, key selection considerations include its 176-pin UFBGA package with 159 5 V-tolerant I/Os, dual Quad-SPI support for external memory expansion, hardware crypto acceleration (AES-256/SHA-2), and dedicated Ethernet MAC with IEEE 1588v2 timing support.

Technical Context

The STM32F479NIH6 integrates an adaptive real-time accelerator (ART Accelerator™) enabling zero-wait-state execution from flash at 180 MHz, alongside a multi-AHB bus matrix for concurrent peripheral access. Its memory subsystem includes dual-bank flash supporting read-while-write and flexible external memory controller (FMC) for SDRAM, PSRAM, and NOR/NAND interfaces.

Graphics processing is offloaded via the Chrom-ART Accelerator™ (DMA2D), while display output is handled by both parallel LCD-TFT (XGA) and MIPI DSI host controllers. The device implements two independent USB OTG controllers - one full-speed with on-chip PHY, one high-speed with ULPI interface and dedicated DMA - plus a 10/100 Ethernet MAC with hardware timestamping for time-sensitive networking.

Key Specifications

Pinout & Package

STM32F479NIH6 is housed in a 10 × 10 mm UFBGA176 package with 0.8 mm ball pitch, optimized for high-density industrial and automotive-grade PCB designs. Thermal performance is enhanced by an exposed thermal pad (EP) under the die.

FAQ

What is the maximum operating temperature range for STM32F479NIH6?

The STM32F479NIH6 is rated for industrial temperature range: –40 °C to +85 °C ambient. This is validated per ST's qualification standard AEC-Q100 Class 2 (for extended temperature variants) and applies to all UFBGA176 packages including the NIH6 suffix. Thermal derating begins above 70 °C ambient when operating at full 180 MHz with all peripherals active.

Does STM32F479NIH6 support external SDRAM, and what interface does it use?

Yes, STM32F479NIH6 supports external SDRAM via its Flexible Memory Controller (FMC) with dedicated 16-bit data bus, row/column address multiplexing, and programmable timing registers. It complies with JEDEC Standard No. 22. A 64 MB SDRAM (e.g., IS42S16400J) is directly compatible using the FMC_SDRAM_BANKx signals mapped to PD0–PD15, PG0–PG15, and PE0–PE15.

How many independent USB interfaces does STM32F479NIH6 provide, and what are their capabilities?

STM32F479NIH6 integrates two physically separate USB controllers: USB_OTG_FS (full-speed only, with on-chip PHY) and USB_OTG_HS (high-speed/full-speed, with ULPI interface and dedicated DMA). The HS controller supports 480 Mbps operation when paired with an external ULPI transceiver, while FS operates standalone - enabling simultaneous host/device roles across different speed domains.

Is the MIPI DSI interface on STM32F479NIH6 implemented with an integrated D-PHY, and what resolutions does it support?

Yes, STM32F479NIH6 includes a fully integrated MIPI DSI host controller with embedded D-PHY compliant transceivers on PH13–PH15 (clock lane) and PH9–PH12 (data lanes). It supports single-lane or dual-lane configurations up to 720p resolution at 30 Hz (1280×720 @ 30 fps), with hardware packet formatting, error detection, and LP-to-HS transition control - no external PHY required.
