This asymmetric architecture lets you run a real-time control loop on the M4 while the M7 handles heavy signal processing or communications stack — no shared-core contention. The 2 MB Flash and 1 MB RAM give enough headroom for a combined application without external memory in many cases. ## Connectivity and peripheral density The 36-channel 16-bit ADC and dual 12-bit DAC cover analog front-end tasks without an external converter. Housed in a 265-ball TFBGA (14x14 mm), the 240+25-ball footprint demands a multi-layer PCB with via-in-pad or microvia capability for signal breakout. This is not a hand-solderable package — plan for reflow assembly and X-ray inspection.","metaTitle":"ST STM32H745XIH3 32-Bit Dual-Core MCU, 240/480 MHz, 2 MB Flash, TFBGA","metaDescription":"STMicroelectronics STM32H745XIH3 dual-core ARM Cortex-M4/M7 MCU. 240 MHz / 480 MHz speed, 2 MB Flash, 1 MB RAM, 168 I/O, -40°C to 125°C.
