UPD75316 Description
The µPD75316(A) is one of the 75X Series 4-bit single-chip microputer having a built-in LCD controller/ driver, and has a data processing capability parable to that of an 8-bit microputer. In addition to high-speed operation with 0.95 µ s minimum instruction execution time for the CPU, the µ PD75316(A) can also process data in 1-, 4-, and 8-bit units. Therefore, as a 4-bit single-chip microputer chip having a...
