Introduction To STM32H7

INTRODUCTION

The STM32H7 is a high-performance 32-bit microcontroller that is based on the Arm Cortex-M7 and Cortex-M4 cores. The Cortex-M7 core operates at up to 480 MHz, while the Cortex-M4 core operates at up to 240 MHz ¹. The STM32H7 series is designed to deliver the maximum theoretical performance of the Cortex-M7 and Cortex-M4 cores ¹. The STM32H7 series includes three product line groups: dual-core lines, single-core lines, and value lines .

The dual-core lines consist of Arm Cortex-M7 and Cortex-M4 cores that can respectively run up to 480 MHz and 240 MHz, enabling more processing and application partitioning . The dual-core STM32H7 product lines are available with an embedded SMPS for improved dynamic power efficiency . The single-core lines offer either great performance at 550 MHz or a unique combination of performance and power saving at 280 MHz and 34 µA (typ) in STOP mode . The value lines are cost-effective STM32H7 devices with an embedded 128 Kbytes Flash memory .
