STM32H7 Product Line Group

The STM32H7 series consists of 3 product line groups:

  • Dual-core lines
  • Single-core lines
  • Value lines

The following is a brief introduction of the 3 product line groups:

STM32H7 Product Line Group: Dual-core lines

STM32H7 Product Line Group: Dual-core Lines

Dual-core lines: Arm® Cortex®-M7 and Cortex®-M4 cores can run up to 480 MHz and 240 MHz, allowing further processing and partitioning of applications. Dual-core STM32H7 product lines are available with built-in SMPS for improved dynamic power efficiency.

STM32H7 Product Line Group: Single-core lines

STM32H7 Product Line Group: Single-core Lines

Single-core lines: Cortex®-M7 offers either excellent performance at 550 MHz or a unique combination of performance and power savings at 280 MHz and 34 μA (type) in STOP mode.

STM32H7 Product Line Group:

STM32H7 Product Line Group: Value Lines

Value lines: with an embedded 128 Kbyte Flash memory, the STM32H750/B0 MCUs are cost-effective STM32H7 devices.

STM32H7 devices embedding a crypto/hash processor support security services such as Secure Firmware Install and Secure Boot – Secure Firmware Upgrade enabling the installation of new application codes in a secured manner.


STM32H7 Advantage

STMicroelectronics STM32H7 High-Performance MCUs are based on the high-performance Arm® Cortex®-M7 32-bit RISC core up to 480MHz. The Cortex-M7 core features a floating point unit (FPU) that supports instructions and data types for Arm double-precision (IEEE 754 compliant) and single-precision data-processing. A full set of DSP instructions and a memory protection unit (MPU) to enhance application security are supported by the STM32H7 MCUs.

The MCUs incorporate high-speed embedded memories with up to 2 Mbytes, 1 Mbyte of RAM with a dual-bank Flash memory (including 192 Kbytes of TCM RAM, 864 Kbytes of user SRAM and 4 Kbytes of backup SRAM). The devices also have a wide range of enhanced I/Os and peripherals connected to APB buses, AHB buses, a 2x32-bit multi-AHB bus matrix and an internal and external memory access supporting multi-layer AXI interconnect.

The devices offer three ADCs, two DACs, two ultra-low power comparators, a low-power RTC, a high-resolution timer, 12 general purpose 16-bit timers, two PWM timers for engine control, five low-power timers and a true random number generator (RNG). The appliances support four external sigma-delta modulator (DFSDM) digital filters and feature standard and advanced communication interfaces.
