The M8051W is an advanced microcontroller core that executes each machine cycle in two clock cycles, achieving a remarkable sixfold increase in performance compared to traditional M8051 and M8052 cores. Intuitive and robust, it maintains binary and memory compatibility with Intel's MCS-51 devices. It additionally supports extended features like multiple data pointers, enhanced interrupt support, optional multi-clock domain utilization for power optimization, and synchronous memory cell compatibility.
