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 (I
O
=–15mA max.)
• Up to five output ports are available (I
O
=–2mA 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
• Built-in RC oscillation circuit for LCD alternating current drive
• Built-in voltage dividing resistor for bias voltage generation
• Power supply voltage : 5V±10%
• Temperature range : –40 to +85°C
• Package:
64-pin plastic QFP (QFP64-P-1414-0.80-BK)(Product name : MSM9006-01GS-BK)
