1. General
description
The EM65168/EM65168A is a dot matrix LCD driver, which is fabricated by low power CMOS
technology. This chip includes 80-bits shift register, 80 bits data latch and 80 bits level driver.
A LCD RAM inside can be mapping to LCD signal. It converts RAM data to parallel data and
output waveform to LCD.
2. Features
(1) Supply power: 2.5~5.5V
(2) LCD drive voltage: 3.6 to 15V
(3) Internal RAM: 6,400 bits
(4) RAM can be controlled by eight signals including 4/8 bits bus.
(5) Duty: 1/32, 1/48, 1/64, 1/80
(6) Build in DC/DC converter: double, triple, quad and five times.
(7) Modularized function: connect to another EM65168/EM65168A to extent LCD matrix
(8) One DC converter enabled and other EM65168/EM65168A can share with this.
(9) Internal regulator output for DC/DC converter controlled by control register.
(10) Bias Selectable: 1/5, 1/6, 1/7, 1/8, 1/9
(11) Internal RC clock about 24 KHz.
(12) CMOS process (P-type silicon substrate)
(13) EM65168A is compatible with EM83040A.
