This split lets the M7 handle heavy number-crunching or real-time control loops while the M4 runs communications stacks or safety monitoring on the same die. The 2 MB Flash (2M x 8) and 1M x 8 RAM provide enough headroom for dual-image firmware updates or large data buffers without external memory. The 148 I/O lines fan out through the 28x28 mm QFP footprint, which is a standard pick-and-place profile for medium-density production. ## Connectivity and analog front-end density Connectivity covers CANbus, Ethernet, USB OTG, multiple SPI/I²C/UART interfaces, plus MMC/SD/SDIO and QSPI for external Flash or SRAM expansion. The 32-channel 16-bit ADC bank and dual 12-bit DACs let this part digest multi-sensor analog inputs without an external multiplexer or separate ADC chip. ## Industrial temperature and lifecycle status The lifecycle is marked as EOL hot — meaning the manufacturer has issued or is about to issue a last-time-buy notice. Procurement should confirm the LTB window and secure bridge-buy quantities before the order code closes.","metaTitle":"ST STM32H755BIT6 Dual-Core MCU, 240MHz/480MHz, 2MB Flash","metaDescription":"STMicroelectronics STM32H755BIT6 dual-core ARM Cortex-M4/M7 MCU in 208-LQFP. 2MB Flash, 1M x 8 RAM, 148 I/O, industrial temp.
