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 5x6 key circuit allows
input through a keyboard, and minimizes the number of wires between the front
panel and CPU.
