Product details

The STM32F779IIT6: ARM Cortex-M7 32-bit MCU at 216 MHz with 2 MB Flash and 512K x 8 SRAM in a 176-LQFP package.

Memory and connectivity headroom

With 512 KB of SRAM (organized as 512K x 8), the STM32F779IIT6 can hold large frame buffers or protocol stacks without off-chip RAM. The 2 MB Flash is sized for a substantial firmware image plus an OTA staging area. Connectivity covers CANbus, Ethernet, USB OTG, QSPI, SAI, SPDIF, and multiple UART/SPI/I²C channels — enough to interface with sensors, displays, and fieldbuses directly. The 24-channel 12-bit ADC and 2-channel 12-bit DAC handle analog signal acquisition and output without an external converter.

Brown-out detection and POR are integrated, reducing external supervisor circuitry.

The base product number is STM32F779, and the family includes multiple density and package variants if a different pin count or memory size is needed.

Frequently asked questions

What is the difference between STM32F779IIT6 and STM32F769IIT6?

Both are STM32F7 series Cortex-M7 MCUs with 216 MHz core speed and 176-LQFP package. The STM32F779IIT6 includes a DSI Host and a JPEG codec that the STM32F769IIT6 lacks, making it better suited for display-intensive applications. Pin compatibility allows a board-level swap if the extra peripherals are not needed.

What are the specifications of STM32F779IIT6?

Peripherals include Ethernet, CAN, USB OTG, QSPI, SAI, and a TFT LCD controller.

What is the equivalent or replacement for STM32F779IIT6?

The closest pin-compatible alternative within the STM32F7 family is the STM32F769IIT6, which shares the same package and core speed but omits the DSI Host and JPEG codec. For a drop-in replacement with identical peripheral set, the STM32F779IIT6 itself is the correct choice; no direct second-source from other manufacturers is listed.
