DATA SHEET
MOS INTEGRATED CIRCUIT
µPD16454A
The µPD16454A is a single-chip controller/driver for dot matrix LCD, enabling the display of up to 48
alphanumerical and kana characters and symbols (24 characters × 2 lines) each of which is composed of 5 × 7 dots.
On-chip charge pump-type DC/DC converter that enables the µPD16454A to operate on a single 5-V power supply
and the chip design aiming at tape carrier package (TCP) mounting make the µPD16454A ideal for portable
equipment and all kinds of data terminals for which downsizing is an important consideration.
