STMicroelectronics STM32F779I-EVAL

Overview

STM32F779I-EVAL from STMicroelectronics is an evaluation board built around the STM32F779NI high-performance ARM® Cortex®-M7 microcontroller featuring 2-Mbyte Flash, 512+16+4-Kbyte RAM, BGA216 package, and integrated ST-LINK/V2-1 debugger. It supports dual USB OTG (HS/FS), MIPI® DSI 4" capacitive touch LCD, Ethernet MAC, dual CAN 2.0A/B, SAI audio DAC, stereo digital microphone, and 8Mx32-bit SDRAM for embedded HMI and multimedia applications.

For engineers reviewing the STM32F779I-EVAL datasheet, STM32F779I-EVAL pinout, STM32F779I-EVAL application, or STM32F779I-EVAL equivalent, this page provides verified hardware interface mapping, memory subsystem configuration, debug connectivity options (JTAG/SWD/ETM), and peripheral validation status for rapid prototyping of industrial HMI, IoT gateway, and real-time multimedia systems.

Technical Context

The board implements the full peripheral suite of the STM32F779NI MCU, including dual USB OTG controllers with Micro-AB connectors, IEEE-802.3-compliant Ethernet PHY interface, FMC supporting SDRAM/SRAM/NOR/NAND, Quad-SPI NOR Flash, and MIPI DSI transmitter driving a 4-inch capacitive touch display. All interfaces are electrically validated and routed to accessible headers.

It integrates ST-LINK/V2-1 as an embedded in-circuit debugger/programmer with SWD and JTAG support, plus ETM trace capability. Power is flexibly supplied via six 5 V sources: power jack, ST-LINK/V2-1 USB, two USB FS ports, USB HS port, and daughterboard connector - enabling isolated domain testing.

FAQ

Does STM32F779I-EVAL include the STM32F779NI MCU pre-soldered?

Yes. The board ships with the STM32F779NIH6 microcontroller (BGA216 package, 2-MB Flash, 512+16+4-KB RAM) fully assembled and tested. No additional MCU purchase or soldering is required for immediate evaluation or firmware development.

Can the MIPI DSI display interface drive third-party 4-inch DSI panels?

Yes. The board's MIPI DSI connector complies with MIPI D-PHY v1.2 and supports standard 4-lane DSI signaling. Panel compatibility depends on timing parameters and command set alignment; ST provides DSI initialization code and register maps in the STM32CubeF7 firmware package.

Is ST-LINK/V2-1 on-board capable of programming external STM32 targets?

Yes. The ST-LINK/V2-1 is exposed via SWDIO/SWCLK/NRST pins on the CN2 header, allowing it to program and debug external STM32 boards. Firmware updates and SWD pin remapping are supported through ST's STSW-LINK007 utility.

What power sources can be used simultaneously without conflict?

The board supports single-source operation only. While six 5 V inputs exist (power jack, ST-LINK USB, USB HS/FS1/FS2, daughterboard), internal diode-OR logic prevents backfeeding. Simultaneous use may cause voltage contention; ST recommends using only one primary source, with others disconnected during operation.
