The Cortex-M23 is a microcontroller core from ARM Holdings’ Cortex family of cores. It is a 32-bit processor with a Harvard architecture, meaning it has separate memory spaces for instructions and data. The Cortex-M23 was first introduced in 2017 as an upgrade to the Cortex-M3 and Cortex-M4 cores. It offers improved performance and additional features compared to its predecessor cores.
The Cortex-M23 core is designed for microcontroller applications and is optimized for low power consumption. It has a Harvard architecture with separate memory spaces for instructions and data. The processor has a three-stage pipeline, with the stages being fetch, decode, and execute. The Cortex-M23 supports a wide range of memory types, including ROM, RAM, flash, and EEPROM. It also has a Memory Protection Unit (MPU) to enable memory protection and isolation.
The Cortex-M23 has a clock speed of up to 120 MHz and can achieve a Dhrystone MIPS (DMIPS) performance of up to 256. It also has a single-cycle MAC (multiply-accumulate) unit, which enables it to perform fast mathematical operations.
It includes the following components:
There are a number of add-ons available for the Cortex-M23 core, including:
