General Description
The HT1620 is a 128 pattern (32´4), memory
mapping, and multi-function LCD driver. The
S/W configuration feature of the HT1620
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 HT1620. The HT1620 consumes low
operating current owing to adopting capacitor
type bias charge pump. The HT162X series
have many kinds of products that match vari-
ous applications.
