H8/300 is a high speed 8-bit CPU with an internal 16-bit architecture.
H8/300 CPU IP is compatible with H8S CPU subsystem IP (H8S C200) on system, bus and interrupt interface. So, it can be used in place of H8S CPU with other peripheral modules of optional information packages. It can optimize CPU subsystem gate size for small systems.
Its instruction set is compatible H8/300 and H8/300L series microcontroller products.
