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.
