The STM32F469IEH6 runs the ARM Cortex-M4 core at 180 MHz, which is the ceiling for this STM32F4 series. That clock rate directly determines how fast the Chrom-ART Accelerator and the LCD-TFT controller can push pixels to a display — critical for GUI-heavy HMI panels or instrumentation screens where frame rate matters. The core also handles Ethernet and USB OTG stacks without stealing cycles from the graphics pipeline, so the 180 MHz rating is the headroom for mixed workloads.
Memory budget: 512 KB Flash, 384 KB RAM
512 KB of Flash stores application code. 384 KB of RAM (384K x 8) supports a double frame buffer at QVGA resolution.
Connectivity and I/O for industrial panels
114 I/O lines are available, along with Ethernet MAC, USB OTG, CAN, multiple SPI and I²C buses, SAI for audio, and SDIO for external storage. That peripheral set is designed for a connected HMI or a gateway that aggregates sensor data over CAN and Ethernet while driving a local display. The 24-channel 12-bit ADC and dual 12-bit DAC handle analog front-end capture and control outputs without an external converter.
201-ball UFBGA (176+25 balls, 10x10 mm body). -40°C to 85°C industrial temperature range. 1.7 V to 3.6 V supply range.
