Product Summary

The GA1621 is a 128 dots (32x4), memory mapping, and multi-function LCD driver. The S/W con-figuration feature of the GA1621 makes it suitable for multiple LCD applications including LCD modules and display subsystems. Only three or four lines are required for the interface between the host controller and the GA1621. The GA1621 contains a power down command to reduce power consumption.
