UC1602i
Single-Chip, Ultra-Low Power
Passive Matrix LCD Controller-Driver
I
UC1602i is an advanced high-voltage mixed-
signal CMOS IC, especially designed for the
display needs of ultra-low power hand-held
devices.
In addition to low power column and row drivers,
these ICs contain all necessary circuits for high-V
LCD power supply, bias voltage generation,
timing generation and graphics data memory.
Advanced circuit design techniques are
employed to minimize external component counts
and reduce connector size while achieving
extremely low power consumption.
