MC68704P2

MOTOROLA· I SEMICONDUCTOR TECHNICAL DATA MC68704P2 TechnicalSummary HMOS Microcomputer Unit MC68704P2 HMOS (high-density NMOS) microcomputer unit (MCU) is an EPROM member of the M6804 Family of microcomputers. 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. This technical summary contains limited information on the MC68704P2. For detailed information, refer to the advanced information data sheet for·the MC6804J1, MC6804J2, MC6804P2, and MC68704P2 8-bit microcomputers, (MC6804J1/D) or to the M6804 MeV Manual (DLE404/D).
