Description
The EK7010 is a 240 output segment/common LCD
driver adaptable to drive a large scale dot matrix panel.
It uses the Tape Carrier Package(TCP) to greatly
reduce the size of the LCD module. EK7010 consumes
very little power. Large LCD panels can be assembled
by cascading EK7010s. In Segment Mode, the input
data can be either 4-bit parallel or 8-bit parallel, selected
by the Mode Select pin (MD).
