TECHNICAL DATA
IZ1621
The IZ1621 is a 128 pattern (32x4), memory mapping, and multi-function LCD driver. The S/W configuration
feature of the IZ1621 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 HT1621. The
IZ1621 contains a power down command to reduce power consumption.
