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.
FEATURES
⢠41 segment outputs (when LED and output port are not used)
A maximum of 123 segments can be dispalyed (MSM9006-01)
A maximum of 164 segments can be displayed (MSM9006-02)
⢠One LED can be driven directly (IO=â15mA max.)
⢠Up to five output ports are available (IO=â2mA to +1mA)
⢠The state of up to 25 key switches can be read through the internal 5 x 5 keyscan circuit
⢠The interface with the CPU is a serial interface using LOAD, DATA I/O, and CLOCK
