FEATURES
SA8806A
64 SEGMENT LIQUID CRYSTAL DISPLA Y DRIVER
P ARALLEL INTERF ACE
n Drives up to 64 segments
n Standard parallel interface
n Operates over a wide temperature
range
DESCRIPTION
The SAMES SA8806A Liquid Crystal
Display (LCD) Driver is capable of driving
up to 64 LCD segments and is designed for
displays having 4 track multiplexed
backplanes.
The SA8806A includes an on-chip
oscillator. The device may be programmed
from a standard µP or µC Bus.
This LCD driver is ideal for any µ-Controller
based system requiring up to an 8 digit
LCD display.
The SA8806A integrated circuit is available
in both 40 pin dual-in-line plastic (DIP-40),
as well as 44 pin plastic leaded chip carrier
(PLCC-44) package types.
