GD32 Arm® Cortex®-M23 Microcontrollers
Arm® Cortex®-M23 is the successor of the Arm® Cortex®-M0 and Cortex®-M0+ which is based on the latest Arm®v8-M architecture of embedded microprocessor cores. It adopts a Von Neumann two-stage pipelined structure and supports the complete Arm®v8-M reference instruction set while maximizing code compactness. Moreover, it is compatible with all Arm®v6-M instructions allowing engineers to easily transfer code from Arm® Cortex®-M0/M0+ processors to the Arm® Cortex®-M23. Additionally, the new Arm® Cortex®-M23 core is equipped with independent resources such as single-cycle hardware multipliers, hardware dividers, hardware frequency dividers, nested vectored interrupt controllers (NVICs), enhancing debug error correction and traceability for easier development. Subsequent products can also benefit from TrustZone® technology designed to support trusted and non-trusted software isolation and protection in hardware and to meet multiple security requirements.
