General Description
The NT7701 is a 160-bit output segment/common driver LSI
suitable for driving the large scale dot matrix LCD panels
used by PDA's, personal computers and work stations for
example. Through the use of SST (Super Slim TCP)
technology, it is ideal for substantially decreasing the size of
the frame section of the LCD module. The NT7701 is good
as both a segment driver and a common driver, and a low
power consuming, high-precision LCD panel display can be
assembled using the NT7701. In the segment mode, the
data input is selected 4bit parallel input mode or as 8bit
parallel input mode by a mode (MD) pin. In common mode,
the data input/output pins are bi-directional and the four data
shift directions are pin-selectable.
