Dual-core architecture — 480 MHz Cortex-M7 plus 240 MHz Cortex-M4
The STM32H757BIT6 is STMicroelectronics' STM32H7 series dual-core microcontroller built around an ARM Cortex-M7 core running at 480 MHz and a Cortex-M4 core at 240 MHz. 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.
