216 MHz Cortex-M7 with 2 MB Flash — processing headroom for signal-chain and HMI
The STM32F777IIT6 runs an ARM Cortex-M7 core at 216 MHz, giving it the throughput to handle real-time control loops alongside a graphical user interface on the LCD controller without a separate graphics processor. With 2 MB of on-chip Flash and 512 KB of SRAM, firmware can carry a full communication stack (Ethernet, CAN, USB OTG) and still leave room for display buffers and data logging.
176-LQFP package — hand-solderable and inspectable
The 176-LQFP (24x24 mm) has a 0.5 mm pitch that a rework station or even a skilled hand with a fine iron can manage — no BGA reball or X-ray inspection required. Surface-mount package means it sits flat on a standard PCB footprint; the 132 I/O lines fan out to the board edge without blind vias.
Industrial temperature grade and active lifecycle
The part is ROHS3 compliant, meeting the current restriction-of-hazardous-substances directive for solderability and environmental compliance.
Connectivity and peripheral set for system-level integration
The STM32F777IIT6 integrates Ethernet MAC, dual CAN interfaces, USB OTG (host and device), plus QSPI for external Flash and SAI for digital audio — enough wired connectivity to serve as the main controller in an industrial gateway or a multi-protocol bridge. Peripherals such as DMA, PWM timers, and a brown-out detector reduce the need for external supervisory ICs, simplifying the BOM count.
