STMicroelectronics STM32F777NIH7

Overview

STM32F777NIH7 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, delivering 462 DMIPS at 216 MHz, 2 MB dual-bank flash, 512 KB + 16 KB + 4 KB RAM, hardware JPEG codec, LCD-TFT and MIPI DSI controllers, and cryptographic acceleration (AES-128/192/256, SHA-1/2, RNG). It targets advanced HMI, industrial control, and multimedia edge nodes requiring real-time graphics, secure connectivity, and multi-interface concurrency.

For engineers reviewing the STM32F777NIH7 datasheet, STM32F777NIH7 pinout, STM32F777NIH7 application, or STM32F777NIH7 equivalent, key selection criteria include its 216 MHz Cortex-M7 core with L1 cache, dual-bank flash for seamless firmware updates, integrated Chrom-ART Accelerator for GUI rendering, triple CAN 2.0B support, and 10/100 Ethernet MAC with IEEE 1588v2 hardware timestamping.

Technical Context

The STM32F777NIH7 implements a tightly coupled memory architecture with 16 KB I/D cache, ART Accelerator, and separate instruction/data TCM RAM (128 KB data + 16 KB instruction) to guarantee zero-wait-state execution of time-critical code. Its AXI-AHB bus matrix enables concurrent access to flash, SRAM, and peripherals without arbitration stalls.

It integrates dual USB OTG controllers (FS with on-chip PHY; HS with ULPI and dedicated DMA), a full-featured 10/100 Ethernet MAC with MII/RMII, three independent CAN 2.0B controllers, and a MIPI D-PHY compliant DSI host supporting up to 720p@30 Hz - all synchronized via multiple PLLs including PLLSAI for audio/LCD clock generation.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the STM32F777NIH7?

The STM32F777NIH7 operates at up to 216 MHz with its Arm Cortex-M7 core, achieving 462 DMIPS (Dhrystone 2.1) at 2.14 DMIPS/MHz. This performance is sustained with zero wait states thanks to the integrated 16 KB I/D cache and ART Accelerator, enabling deterministic execution of real-time control and graphics workloads.

Does the STM32F777NIH7 support hardware-accelerated JPEG encoding or decoding?

Yes, the STM32F777NIH7 includes a dedicated hardware JPEG codec capable of both encoding and decoding JPEG images. It supports baseline JPEG syntax and operates independently of the CPU, freeing the Cortex-M7 core for application logic while accelerating image compression/decompression for camera interfaces or display frame buffering.

How many CAN interfaces does the STM32F777NIH7 integrate, and what protocol versions are supported?

The STM32F777NIH7 integrates three fully independent bxCAN 2.0B controllers, each supporting CAN 2.0A and 2.0B protocols with programmable bit rates up to 1 Mbps. Each controller features dedicated message RAM, flexible filtering, and automatic retransmission - enabling concurrent operation on separate CAN networks without CPU intervention.

What package type and pin count does the STM32F777NIH7 use, and is it 5 V-tolerant?

The STM32F777NIH7 uses a 176-ball UFBGA package (10 mm × 10 mm, 0.8 mm pitch) with 166 5 V-tolerant I/O pins. This tolerance allows direct interfacing with legacy 5 V peripherals without level-shifting circuitry, simplifying design integration in mixed-voltage industrial systems.
