RAM Mapping 32 X 4 LCD Controller for I/O uC
***********************************************************************************************************
General Descriptions
The SS1621 is a 128-pattern (32x4), memory mapping, and multi-function LCD driver. The
S/W configuration feature of the SS1621 makes it suitable for multiple LCD applications including
LCD modules and display subsystems. Only three or four lines are required for the interface be-
tween the host controller and the SS1621. The SS1621 contains a power down command to reduce
power consumption.
