GENERAL DESCRIPTION
The EM65160 is a 160-channel output common and segment driver LSI for driving large scale STN dot matrix LCD (liquid
crystal display) panel using as PDA, computers and workstation. Since this product can be used as segment or common
driver, a LCD panel can be configured only with this product. Through the use of SST (super slim TCP) technology, it is deal
for substantially decreasing the size of LCD module frame.
In common driver mode, it can be selected in single mode and dual mode by a mode pin (MD), data input/output pins are
bi-directional, four data shift direction are pin selectable.
In segment driver mode, it can be selected 4-bit parallel input mode or 8-bit parallel input mode by a mode pin (MD).

Automatic transfer function of an enable signal
-
Automatic counting function which, in the chip select, causes the internal clock to be stopped by automatically counting
160 of input data
-
Line latch circuit reset function when /DSPOF active
