DESCRIPTION
The µPD75316(A) is one of the 75X Series 4-bit single-chip microcomputer having a built-in LCD controller/driver, and has a data processing capability comparable to that of an 8-bit microcomputer.
In addition to high-speed operation with 0.95 µs minimum instruction execution time for the CPU, the µPD75316(A) can also process data in 1-, 4-, and 8-bit units. Therefore, as a 4-bit single-chip microcomputer chip having a built-in LCD panel controller/driver, its data processing capability is the highest in its class in the world.
