Abstract
A microcomputer that is easy to use and connected direct to such memories as dynamic and static RAM's and to other peripheral circuits. The microcomputer has strobe signal output terminals CASH*, CASL* and RAS* for direct connection to a dynamic RAM, and chip select signal output terminals CS0* through CS6* for outputting a chip select signal in parallel with the output from the strobe signal output terminals. The microcomputer further includes address output terminals for outputting a non-multiplexed or multiplexed address signal as needed, and data I/O terminals for selectively outputting the address signal to comply with a multiple-bus interface scheme.
