550 MHz Cortex-M7 — compute headroom for real-time control
That core speed puts it in the performance tier for applications that need deterministic signal processing or fast loop closure — think motor-field-oriented control, digital power conversion, or audio effects processing where a 200 MHz part would leave no margin for the control law plus stack overhead. The 1 MB Flash and 564K x 8 RAM give enough room for a real-time OS, a moderate application image, and several large data buffers without external memory.
A 3.3 V system can run the MCU directly; a 1.8 V core-only design saves power.
Connectivity set — Ethernet, CAN, USB OTG on one chip
With Ethernet MAC, two CANbus interfaces, USB OTG, and a full suite of serial peripherals (SPI, I²C, UART, SAI, SPDIF), this MCU can serve as the central node in an industrial control network or a gateway aggregating sensor data. The EBI/EMI interface also supports external SRAM or NOR Flash if the on-chip 1 MB Flash and 564K x 8 RAM aren't enough.
144-LQFP — 80 I/O in a hand-solderable package
The 144-LQFP (20x20 mm) package exposes 80 I/O pins, enough for a parallel LCD, external memory bus, and multiple sensor interfaces without multiplexing. The LQFP footprint is inspectable and reworkable with standard soldering equipment, unlike a BGA, which simplifies prototype builds and low-volume production.
The 12-bit and 16-bit ADCs (12x12b, 18x16b) and dual 12-bit DACs handle analog sensor acquisition without an external converter.
STMicroelectronics lists the STM32H723ZGT6 as Active.
