General Description
The HT1621 is a 128 pattern (32 4), memory
mapping, and multi-function LCD driver. The
S/W configuration feature of the HT1621
makes it suitable for multiple LCD applica-
tions including LCD modules and display sub-
systems. Only three or four lines are required
for the interface between the host controller
and the HT1621. The HT1621 contains a power
down command to reduce power consumption.
