MOS INTEGRATED CIRCUIT

µPD75312B, 75316B

4-BIT SINGLE-CHIP MICROCOMPUTER

The µPD75316B is a 75X Series 4-bit single-chip microcomputer capable of the same data processing as an 8-

bit microcomputer.

It is a low-voltage operation version of the µPD75316 with an on-chip LCD controller/driver. Operation at an ultra-

low voltage of 2.0 V is possible. An ultra small-sized plastic TQFP (12 x 12 mm) is also provided and it is suitable

for small-sized sets that use an LCD panel.

A detailed explanation of the functions will be given in the user's manual listed below. It should be read before

starting design work.
