V850E2/Mx4

The V850E2/Mx4 is a 32-bit single-chip microcontroller that integrates up to two V850E2M 32-bit RISC CPU cores, which were developed by enhancing the performance of the V850E1 CPU and V850E2 CPU. The V850E2/Mx4 includes flash memory, RAM, and various peripheral functions, and is used to perform large-capacity data processing and advanced real-time control.
