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.
