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.
