Description

General part information

STM32H503CB Series

The STM32H503xx devices are a high-performance microcontrollers family (STM32H5 series) based on the high-performance Arm®Cortex®-M33 32-bit RISC core. They operate at a frequency of up to 250 MHz.

The Cortex®-M33 core features a single-precision floating-point unit (FPU) that supports all the Arm®single-precision data-processing instructions and all the data types.

The Cortex®-M33 core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security.
