LC7930N, 7930NW
LCD Drivers
Overview
The LC7930N, 7930NW are CMOS LSIs which incorporate
20-bit shift register, latch, and two sets of 20 LCD drivers.
They also have two switching pins: one of them (channel 2)
can be used as a scan-line driver (back plate) and the other
(channel 1) as a segment driver. They are optimal for LCD
interface with microcontroller (4 or 8 bits) or dot matrix
controller circuit incorporating character generator.
Package Dimensions

3055A-QFP60C
[LC7930N]
Features
. Two channels of 20 output segment drivers
. The configuration of 20 output segment drivers + 20
. scanning terminal drivers available
A series data to connect with the microcontroller and three
control signals
. Able to be connected in series for large display
. Built-in bidirectional shift register can be shifted in the
. direction that makes wiring easy
Operating supply voltage/ Operating temperature:
. VDD = 4.5 to 5.5 V / Topr = –20 to +75°C
Operating current drain : IDD = 1.0 mA max
. (Logic = 400 kHz, LCD = 1 kHz)
