NT7702

240 Output LCD Segment/Common Driver

Features

(Segment mode)

! Shift Clock frequency:

20 MHz (Max.) (VDD = 5 V ± 10%)

! Adopts a data bus system

! 4-bit/8-bit parallel input modes are selectable with a

mode (MD) pin

! Automatic transfer function with an enable signal

! Automatic counting function when in the chip select

mode, causes the internal clock to be stopped by

automatically counting 240 bits of input data

(Common mode)

! Shift clock frequency :

4.0 MHz (Max.)

! Built-in 240-bits bidirectional shift register (divisible into

120-bits x 2)

General Description

The NT7702 is a 240-bit output segment/common driver LSI

suitable for driving large scale dot matrix LCD panels using

as PDA/personal computers/work stations. 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 NT7702 is good as both a segment driver

and as a common driver, and a low power consuming, high-

precision LCD panel display can be assembled using the

NT7702. In the segment mode, the data input is selected as

4bit parallel input mode or as 8bit parallel input mode by a

mode (MD) pin. In the common mode, the data input/output

pins are bi-directional and the four data shift directions are

pin-selectable.
