⚡ STMicroelectronics launches STM32H7P4 and STM32H7P5 MCUs

STMicroelectronics has introduced the STM32H7P4 and STM32H7P5, two 520 MHz Arm Cortex-M7 MCUs designed for digital power, motor control, industrial sensing, and edge AI applications. These components belong to the STM32H7P family and feature a Hardware Signal Processor (HSP) to accelerate mathematical and signal-processing operations. The STM32H7P5 variant additionally includes an 85 GOPS Neural-ART NPU for Edge AI inference and TinyML tasks.

Both microcontrollers integrate up to 2MB of dual-bank flash memory and 736KB of SRAM. Timing capabilities include two high-resolution timers with up to 24 PWM outputs, three advanced motor-control timers, and four 12-bit ADCs. The architecture supports external memory through Octo-SPI and FMC interfaces, alongside three CAN FD interfaces and USB OTG Full-Speed connectivity.

The core consists of a 32-bit Arm Cortex-M7 CPU running at up to 520 MHz with a double-precision FPU, DSP instructions, and an MPU. It includes 32 KB instruction cache and 32 KB data cache, achieving 2773 CoreMark performance at 5.33 CoreMark/MHz. Mathematical coprocessors such as CORDIC and FMAC accelerators are also present to support complex calculations.
