The STMicroelectronics STM32F769BIT6 is a high-performance 32-bit Arm Cortex-M7 microcontroller from the STM32F7 family, designed for graphics-rich embedded systems, industrial HMIs, connected devices, instrumentation and other applications requiring high processing performance and extensive peripheral integration.
The Cortex-M7 CPU operates at up to 216MHz and includes a double-precision and single-precision floating-point unit (FPU), DSP instruction support, a Memory Protection Unit (MPU), ART Accelerator and 16KB instruction / 16KB data L1 cache. ST specifies performance up to approximately 462 DMIPS / 2.14 DMIPS per MHz.
The STM32F769BIT6 integrates 2MB of embedded Flash memory organized in two banks with read-while-write capability. Its high-speed RAM architecture includes 512KB SRAM, including 128KB Data TCM RAM, together with 16KB Instruction TCM RAM and 4KB backup SRAM for low-power backup applications.
A major strength of the STM32F769 family is its integrated graphics subsystem. The device includes the Chrom-ART Accelerator (DMA2D) for accelerating graphical operations, an LCD-TFT controller supporting up to XGA resolution, a MIPI-DSI Host controller supporting up to 720p at 30Hz, and a hardware JPEG codec. These functions make it particularly suitable for embedded graphical user interfaces and industrial display systems.
For external memory expansion, the MCU provides a flexible memory controller supporting SRAM, PSRAM, NOR Flash, NAND Flash and SDRAM, together with dual-mode Quad-SPI for high-speed external Flash access.
The analog subsystem includes three 12-bit ADCs with up to 2.4MSPS conversion speed and up to 24 channels, two 12-bit DACs, and an 8-channel DFSDM digital filter block with four filters, making the device suitable for mixed-signal measurement, audio and sensor-processing applications.
The STM32F769BIT6 also provides extensive wired connectivity. Available interfaces include 10/100 Ethernet MAC with IEEE 1588v2 hardware support, USB 2.0 Full-Speed OTG with integrated PHY, USB 2.0 High-Speed/Full-Speed OTG with ULPI support, up to 3 CAN 2.0B interfaces, 2 SDMMC interfaces, multiple I2C, SPI, USART, UART, SAI and I2S interfaces, together with HDMI-CEC and SPDIFRX support.
Additional peripherals include a digital camera interface, true random-number generator, CRC unit, RTC, numerous 16-bit and 32-bit timers, watchdog timers, DMA controllers and SWD/JTAG debugging support.
The device operates from a 1.7V to 3.6V application supply and supports Sleep, Stop and Standby low-power modes.
The specific STM32F769BIT6 ordering code uses a 208-pin LQFP package measuring 28 × 28 × 1.4mm and is specified for the -40°C to +85°C industrial temperature range. ST currently classifies this exact part number as NRND — Not Recommended for New Design, while continuing volume production to support existing customer designs.
