Product Summary

The HT1621B is a 128 pattern (32x4), memory mapping, and multi-function LCD driver. The S/W configuration feature of the device makes it suitable formultiple LCD applications including LCD modules and display sub-systems. Only three or four lines are required for the interface between the host controller and the HT1621B. The device contains a power down command to reduce power consumption.
