The 216 MHz core speed, combined with the Cortex-M7's single-cycle multiply-accumulate and hardware floating-point unit, gives this part a deterministic compute budget for motor-field-oriented control loops, audio codec pipelines, and protocol-stack processing. The 2 MB Flash density supports large firmware images with OTA update staging, while the 512 KB RAM handles Ethernet TCP/IP buffers, USB descriptor tables, and display framebuffers without external SRAM. Operating temperature spans -40 to 105°C, the industrial-grade range that covers outdoor telecom cabinets, factory-floor motor drives, and under-hood automotive auxiliary modules. ## 176-LQFP footprint and I/O count Housed in a 176-LQFP package (24×24 mm body), the STM32F777IIT7 brings out 132 I/O pins. The fine-pitch (0.5 mm) QFP requires a multilayer PCB with dedicated power and ground planes to manage the simultaneous switching noise from the high-speed I/O banks. Decoupling should follow the STM32F7 hardware development guide: one 100 nF ceramic per VDD/VSS pair plus a bulk 4.7 µF to 10 µF on each supply rail. The 132 I/O count, combined with the peripheral multiplexing, allows parallel LCD interfaces, external memory buses (EBI/EMI), and multiple serial ports to coexist. The 24×24 mm package footprint is compatible with standard QFP soldering profiles; ## Connectivity: Ethernet, USB OTG, and serial interfaces The STM32F777IIT7 integrates a 10/100 Ethernet MAC with dedicated DMA and an internal PHY interface (MII/RMII), plus a USB OTG controller that supports host, device, and OTG modes. These two interfaces make this MCU a natural fit for industrial IoT gateways, protocol converters, and edge nodes that bridge fieldbus networks to Ethernet or USB-connected hosts. Additional connectivity includes CANbus, I²C, SPI, UART/USART, SAI (serial audio), SPDIF, QSPI, and SDIO. The QSPI interface can execute code from external Flash at 104 MHz, useful when the 2 MB internal Flash is fully consumed by the application image. The base product number is STM32F777, which shares pin-compatibility with the STM32F767 series in the same 176-LQFP package. If a design needs to scale memory or peripheral count, the STM32F7 family offers density and feature variants that can drop into the same footprint with firmware adjustments.","metaTitle":"STM32F777IIT7 ARM Cortex-M7 MCU, 216MHz, 2MB Flash, 176-LQFP","metaDescription":"STMicroelectronics STM32F777IIT7 32-bit ARM Cortex-M7 MCU at 216MHz with 2MB Flash, 512KB RAM, Ethernet, USB OTG, -40 to 105°C, 176-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"216MHz","Series":"STM32F7","Package":"Tray","RAM Size":"512K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, MMC/SD/SDIO, QSPI, SAI, SPDIF, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"132","Core Processor":"ARM® Cortex®-M7","Package / Case":"176-LQFP","Product Status":"Active","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F777","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"176-LQFP (24x24)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.4328","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ffe57371c27dd3c848e299d72dd90543.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F777IIT7/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F777IIT7 have Ethernet and USB OTG?","answer":"Yes, the STM32F777IIT7 integrates a 10/100 Ethernet MAC with MII/RMII interface and a USB OTG controller supporting host, device, and OTG modes, along with CANbus, I²C, SPI, UART, SAI, SPDIF, QSPI, and SDIO."},{"question":"Is STM32F777IIT7 compatible with STM32F767?","answer":"The STM32F777 and STM32F767 series share pin-compatibility in the same 176-LQFP package.
