This asymmetric multiprocessing arrangement lets the M7 handle heavy number-crunching — real-time control loops, FFTs, or sensor fusion — while the M4 takes on communications stack or low-power housekeeping tasks. With 2 MB of Flash and 1 MB of RAM on-chip, most designs can skip external memory for the firmware image and data buffers, keeping the BOM compact. ## Peripheral set and connectivity for industrial systems On-chip data converters include 32 analog inputs through a 16-bit ADC and two 12-bit DAC channels. This peripheral density suits a single-chip controller for motor drives, PLCs, or HMI panels where the board area is tight. Housed in a 208-pin LQFP (28x28 mm body), the part is a surface-mount device that reflows with standard lead-free profiles. Supply voltage spans 1.62 V to 3.6 V, allowing operation from a single 3.3 V rail or a 1.8 V core supply with separate I/O voltage. ## Lifecycle and sourcing posture This is a production-grade part suitable for new designs and long-running programs.","metaTitle":"STM32H757BIT6 STM32H7 Dual-Core MCU, 480MHz, 2MB Flash","metaDescription":"STM32H757BIT6 32-bit dual-core ARM Cortex-M4/M7 MCU. 480MHz/240MHz speed, 2MB Flash, 1MB RAM, 148 I/O, -40°C to 85°C.
