GENERAL DESCRIPTION

The MSM9006-01 is an LCD driver for a 1/3 duty dynamic display. It can directly drive an LCD with a maximum of 123 segments.

The MSM9006-02 is an LCD driver for a 1/4 duty dynamic display, and can directly drive an LCD with a maximum of 164 segments.

The MSM9006-01, -02 are capable of directly driving one LED, and up to five ports can be used by simply switching the LCD pin.

The internal 5 x 5 keyscan circuit enables keyboard input, decreasing the number of interconnections between the front panel and the CPU.
