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
applications including LCD modules and display sub-
systems. Only three or four lines are required for the in-
terface between the host controller and the HT1621.
The HT1621 contains a power down command to re-
duce power consumption.
