Arm® Cortex®-M33 MCU

GD32 Arm®  Cortex®-M33 Microcontrollers

Cortex®-M33 core is based on the latest Armv8-M architecture. System frequency supports up to 180MHz, includes a built-in hardware multiplier/divider, DSP instruction set and single-precision floating-point unit (FPU). It is also equipped with a new hardware trigonometric math unit (TMU) that supports vector, sine and cosine, exponent, square root, common logarithm and other mathematical trigonometric operations, reducing the burden on the CPU and improving the processing efficiency. These advance features will benefit advanced computing applications centered on digital signal processing. The series provides the highest performance at 244DMIPS and its CoreMark® test can reach 547 points. Compared with similar Cortex®-M4 products in the market, the code execution efficiency under the same main system frequency is improved by 10%-20% and compared with similar Cortex®-M23 products, the performance has been improved by more than 40%.
