Product details

It packs 2 MB of Flash and 512 KB of SRAM, giving firmware teams room for a real-time OS, a GUI library, or a TCP/IP stack without squeezing into a smaller part. The 176-pin LQFP package brings out 140 I/O lines, so you can wire up a parallel LCD, an external memory bus (EBI/EMI), and still have pins left for sensors and actuators. Connectivity covers Ethernet MAC, CAN, USB OTG, Quad-SPI, SAI, SPDIF, and multiple UART/SPI/I²C interfaces — it is designed for the kind of system that bridges a fieldbus to a display and logs data over Ethernet.

Active lifecycle — no last-time-buy scramble

If you are building a BOM that needs to stay stable for a multi-year product, this is a safer pick than an NRND or phase-out part.

That includes factory-floor controllers, outdoor gateways, and engine-bay-adjacent electronics that see cold starts and hot afternoons.

The 176-LQFP (24x24 mm body) is a hand-solderable and inspectable package — no BGA rework station needed. That matters for prototyping, rework, and low-volume production where you cannot justify X-ray inspection.

Frequently asked questions

What is the maximum clock frequency of the STM32F769IIT6?

The STM32F769IIT6 is rated for a 216 MHz core clock. That is the maximum operating frequency for the ARM Cortex-M7 core on this part.

Can the STM32F769IIT6 replace the STM32F746IIT6?

The STM32F769IIT6 is a higher-performance member of the same STM32F7 family, with a 216 MHz Cortex-M7 core versus the STM32F746's 216 MHz (same speed grade) but with additional features like a hardware JPEG codec and a larger RAM. Pin compatibility depends on the specific package variant — the 176-LQFP versions share the same footprint, but verify the peripheral mapping in the reference manual before swapping.

How many GPIO pins does the STM32F769IIT6 have?

The STM32F769IIT6 provides 140 I/O pins in the 176-LQFP package. That count includes all GPIOs plus alternate-function pins shared with the peripheral set.
