LCD 驱动电路
GA1621General Description
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.

The mode command should be issued before the data or command is transferred. If successive commands have been issued,
the command mode ID, namely 1 0 0, can be omitted. While the system is operating in the non-successive command or the
non-successive address data mode, the CS- pin should be set to “1” and the previous operation mode will be reset also. Once the
CS- pin returns to “0” a new operation mode ID should be issued first.
