Product details

It packs 2 MB of Flash and 512K x 8 of SRAM, giving firmware teams room for complex protocol stacks, OTA update staging, or frame buffers without external memory. The 159 I/O lines in a 216-TFBGA package (13x13 mm) allow dense peripheral integration on a compact board — useful for HMI panels or multi-axis drives where every pin counts.

Combined with the 512K x 8 SRAM, you can hold a sizeable data buffer for encoder feedback or waveform synthesis without cache-thrashing. The 2 MB Flash supports in-application programming via the built-in bootloader, so field firmware updates over Ethernet or CAN are practical.

Package and footprint — 216-TFBGA

The 159 GPIOs fan out to the outer balls, making layout feasible on a 4-layer board with careful via fanout.

Frequently asked questions

What are the differences between STM32F777NIH6 and STM32F767NIH6?

Both are 216 MHz Cortex-M7 MCUs in the same package and pin count. The STM32F777 adds a hardware cryptographic accelerator and a true random number generator (TRNG) that the STM32F767 lacks. For designs needing on-chip AES, 3DES, or SHA acceleration without a software library, the STM32F777NIH6 is the correct choice. Pin-compatible between the two, so a board can be laid out for either variant.
