GENERAL DESCRIPTION

The MSM6606 is an LCD driver for a 1/2 duty dynamic display. It can directly drive an LCD of up to 80 segments, and one LED. Keyboard input is now available by the internal 5 x 6 keyscan circuit, and the number of wires between the front panel and the CPU can be minimized.

FEATURES

• Power supply voltage : 5V ± 10

• Temperature range : –40 to +85°C

• Can display an LCD of up to 80 segments (1/2 duty dynamic drive)

• Can directly drive one LED (IO = –15 mA max.)

• Internal 5 x 6 keyscan circuit allows reading of the status of up to 30 key switches

• A serial interface with the CPU is implemented by LOAD, DATA I/O, and CLOCK

• Built-in RC oscillation circuit for LCD alternating current drive

• Built-in voltage dividing resistor for bias voltage generation

• Package:

64-pin plastic QFP (QFP64-P-1414-0.80-BK) (Product name : MSM6606GS-BK)
