UPD75312B Datasheet (NEC) - 4-BIT SINGLE-CHIP MICROCOMPUTER

UPD75312B, 4-BIT SINGLE-CHIP MICROCOMPUTER

DATA SHEET 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 8bit microcomputer.

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

Operation at an ultralow 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.
