Overview

The STM32H723ZGI6 is a high-performance 32-bit microcontroller based on the ARM Cortex-M7 core operating at speeds up to 550MHz. It features 1MB of Flash memory and 564KB of RAM, providing the computational overhead necessary for complex real-time applications and signal processing. The device includes specialized hardware accelerators like the Chrom-ART for graphics and CORDIC for mathematical operations.

Why Choose This Part

This MCU offers a significant performance boost with its 550MHz core and specialized math accelerators (CORDIC and FMAC) that offload the CPU. The 144-pin UFBGA package provides 114 I/Os in a compact 7x7mm footprint, making it ideal for space-constrained high-performance designs. It also features ECC on memories to ensure high reliability in critical industrial and automotive environments.
