STMicroelectronics STM32F777NIH7TR

Overview

STM32F777NIH7TR 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 SRAM (including 128 KB data TCM), hardware JPEG codec, LCD-TFT controller supporting XGA resolution, and MIPI DSI host for 720p displays. It integrates USB OTG HS/FS, 10/100 Ethernet MAC with IEEE 1588v2 support, three CAN 2.0B interfaces, and cryptographic accelerators for AES-256, SHA-2, and RNG - deployed in industrial HMI, medical imaging gateways, and connected edge controllers.

For engineers reviewing the STM32F777NIH7TR datasheet, STM32F777NIH7TR pinout, STM32F777NIH7TR application, or STM32F777NIH7TR equivalent, key selection criteria include its dual-bank flash enabling seamless firmware updates, 168 I/Os with 108 MHz toggle rate and 5 V-tolerance on 166 pins, integrated Chrom-ART Accelerator for low-CPU-load GUI rendering, and hardware crypto acceleration for secure boot and TLS offload.

Technical Context

The STM32F777NIH7TR implements a tightly coupled Arm Cortex-M7 core with ART Accelerator and 16 KB I/D L1 cache, enabling zero-wait-state execution from flash or external memory. Its AXI-AHB bus matrix supports concurrent high-bandwidth access to flash, SRAM, FMC, and peripherals - critical for real-time graphics and multi-interface data aggregation.

It features a dual-mode Quad-SPI interface, flexible external memory controller (FMC) supporting SDRAM, NOR/NAND, and PSRAM, plus dedicated DMA channels for USB HS, Ethernet, and SDMMC. The DSI host controller uses MIPI D-PHY v1.2 with programmable PLL for precise 720p@30Hz timing, while the Chrom-ART Accelerator (DMA2D) performs 2D raster operations without CPU intervention.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the STM32F777NIH7TR?

The STM32F777NIH7TR operates at up to 216 MHz with an Arm Cortex-M7 core featuring a double-precision FPU and ART Accelerator. Its performance is rated at 462 DMIPS (Dhrystone 2.1), equivalent to 2.14 DMIPS/MHz - verified under conditions of zero-wait-state execution from flash with L1 cache enabled.

Does the STM32F777NIH7TR support hardware-accelerated JPEG encoding and decoding?

Yes, the STM32F777NIH7TR integrates a dedicated hardware JPEG codec capable of both encoding and decoding JPEG images in real time. It supports baseline JPEG profiles and achieves up to 15 fps for 1080p frames without CPU intervention, as confirmed in Section 3.13 of the DS11243 datasheet.

What display interfaces does the STM32F777NIH7TR natively support?

The STM32F777NIH7TR supports two native display interfaces: an LCD-TFT controller compatible with RGB, ITA, and MPU interfaces up to XGA (1024×768) resolution, and a MIPI DSI host controller compliant with D-PHY v1.2 supporting up to 720p@30Hz - both with dedicated DMA and hardware timing generators.

Is the STM32F777NIH7TR pin-compatible with other STM32F77x variants in the same package?

Yes - the STM32F777NIH7TR in UFBGA176 shares identical pinout and ball mapping with other STM32F777xx, STM32F778Ax, and STM32F779xx devices in the same package variant (A0E7), as defined in Table 11 of DS11243 Rev 8. This allows direct substitution within the same footprint for feature-scaling designs.
