This asymmetric architecture lets you partition a time-critical control loop (motor FOC, sensor fusion) on the M4 while the M7 handles heavy compute or graphics — no external companion chip needed. The 2 MB Flash and 1M x 8 RAM give enough headroom for dual-boot firmware or a large display buffer without adding external memory. Packaged in a 176+25 UFBGA (10x10 mm), it brings out 128 I/O and a full connectivity set: Ethernet, dual CAN, USB OTG, multiple SPI/I²C, SAI, SPDIF, and a flexible external memory interface (EBI/EMI, QSPI). The 36-channel 16-bit ADC and dual 12-bit DAC handle analog front-end tasks without an external converter. Rated for -40°C to 85°C operation with a supply range of 1.62 V to 3.6 V, it fits industrial enclosures, outdoor telecom cabinets, and motor-drive environments where temperature swings are routine. ## 240 MHz / 480 MHz — what the speed split means for your task allocation The M7 core runs at 480 MHz; the M4 core runs at 240 MHz. The M7 handles floating-point math and Ethernet stack; the M4 runs control loops or safety monitoring.","metaTitle":"ST STM32H745IIK6 32-Bit Dual-Core MCU, 240/480 MHz","metaDescription":"STM32H745IIK6 dual-core ARM Cortex-M4/M7 MCU: 240 MHz / 480 MHz, 2 MB Flash, 1M x 8 RAM, 128 I/O, UFBGA176+25.
