The STM32F777ZIT6 is an STMicroelectronics 32-bit MCU built around the ARM Cortex-M7 core running at 216 MHz, with 2 MB of Flash and 512K x 8 of RAM. It sits in the STM32F7 series, targeting applications that need DSP-class compute and rich connectivity on a single chip — think industrial motor drives, PLCs, building automation gateways, or Ethernet-connected sensor hubs. The 144-LQFP package (20x20 mm) gives 114 I/O, enough for parallel LCD or external memory buses alongside the usual serial interfaces.
Connectivity and peripheral set — one-chip gateway capability
That means it can serve as a protocol bridge or edge node without an external host MCU.
ST lists the STM32F777ZIT6 as Active. The base product number STM32F777 shares the same pinout and memory map across the F7 family, which simplifies second-sourcing within the series if volumes shift.
Temperature grade and supply — industrial cabinet or outdoor telecom
ROHS3 compliant — no lead or restricted substances in the package.
