Product Overview:

The H8S/2239 Group, H8S/2238 Group, H8S/2237 Group, and H8S/2227 Group are high-performance microcomputers made up of the internal 32-bit configuration H8S/2000 CPU as their cores, and the peripheral functions required to configure a system.
A single-power flash memory version and masked ROM version are available for these LSI's ROM. These versions provide flexibility as they can be reprogrammed in no time to cope with all situations from the early stages of mass production to full-scale mass production.
This is particularly applicable to application devices of which the specifications frequently changeable.
