MBL8042N

Advanced Products MBL8042H/N NMOS Universal Peripheral Interface 8-Bit Microcomputer FUJITSU October 1986 Edition 2.0 Description The MBL8042 Universal Penpherallnterface is a single-chip 8-bit microcomputer based on an 8-bit parailel microprocessor chip. The MBL8042 is fabricated with an N-channel silicon-gate MOS process. The MBL8042 has a 2K x 8-bit ROM for program memory, a 128 x 8-bit RAM for data memory, 18 I/O ports, an 8-bit timer/ counter and clock generator on the chip, and is powered by single +5V.supply. The MBL8042 is designed to operate as a slave processor, which receives commands and data from the master processor, controls peripheral devices and transfers input data from peripheral devices to the master processor. By using the MBL8042 an intelligent peripheral controiler can be designed freely. --~:/Y~~~ - mIl - - -D""'-P::&OC, .A01 r--- - Features Processor: 8-bit parallel processing Register: One 8-bit Status Register (lor Interface with master ...
