General Description
The HT1629G is a memory mapping and multi-
function LCD controller driver which can be switched
to either 1/1 or 1/2 duty. It can display up to 240
patterns with a 1/1 duty or 480 patterns with a 1/2
duty driver output. It supports a common driver
output mode segment / LED driver. The software
configuration features of the device makes it suitable
for multiple LCD applications including LCD
modules and display subsystems.
The HT1629G is compatible with most micro-
controllers and communicates via a three-line SPI
interface.
