MSM6606
80-DOT LCD DRIVER WITH KEY MATRIX
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 (I
= –15 mA max.)
O
• 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)
1/18
