Keyscan Function
Documents
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.
