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