1/3, 1/4 DUTY LCD DRIVER WITH 4-DOT COMMON DRIVER AND 29-DOT SEGMENT DRIVER
GENERAL DESCRIPTION
The MSM6786 is a dynamic display LCD driver and can be switched to 1/3 or 1/4 duty. It can dis-play up to 116 segments with 1/4 duty and up to 87 segments with 1/3 duty. It can also drive one LED directly. The built-in 5¥6 key circuit allows input through a keyboard, and minimizes the number of wires between the front panel and CPU.
FEATURES
· Power suppy voltage : 5V±10% · Operating temperature : 40 to +85°C · 29-output segment driver 1/4 duty dynamic drive : Up to 116 segments can be displayed 1/3 duty dynamic drive : Up to 87 segments can be displayed · One LED can be driven directly (IO=15mA max) · Built-in 5¥6 key scan circuit allows reading of the operation status of up to 30 switches. · Interface with CPU is implemented by LOAD, DATA I/O and CLOCK in serial method. · Built-in RC oscillator for LCD AC drive · Built-in voltage dividing resistor for bias voltage generation · Package: 56-pin plastic QFP (QFP56-P-910-0.65-2K) (Product name : MSM6786GS-2K)
