The PD16454A 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 x 2 lines) each of which is composed of 5 x 7 dots. On-chip charge pump-type DC/DC converter that enables the PD16454A to operate on a single 5-V power supply and the chip design aiming at tape carrier package (TCP) mounting make the PD16454A ideal for portable equipment and all kinds of data terminals for which downsizing is an important consideration.
