50X MSM6606 lcd and keypad controller, 3-wire interface

datasheet: http://jc-hp.tripod.com/data/MSM6606.pdf
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.
• Temperature range : –40 to +85
• Can display an LCD of up to 80 segments (1/2 duty dynamic drive)
• Can directly drive one LED (I
• 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)
