TECHNICAL DATA
Technical Summary HMOS Microputer Unit
MC68704P2 HMOS (high-density NMOS) microputer unit (MCU) is an EPROM member of the M6804 Family of microputers. User programmable EPROM allows program changes and lower volume applications. This feature further heightens the versatility of an MCU whose design-ability to process 8-bit variables, one bit at a time, already makes it tremendously cost effective.
