HD66503
(240-Channel Common Driver with Internal LCD
Timing Circuit)
Description
The HD66503 is a common driver for liquid crystal dot-matrix graphic display systems. This device
incorporates a 240 liquid crystal driver and an oscillator, and generates timing signals (alternating signals
and frame synchronizing signals) required for the liquid crystal display. It also achieves low current
consumption of 100 µA through the CMOS process. Combined with the HD66520, a 160-channel column
driver with an internal RAM, the HD66503 is optimal for use in displays for portable information tools.
