FEDL6606-03 ¡ Semiconductor FEDL6606-03 This version: Sep. 2000 MSM6606 Previous version: Nov. 1997 June 1992 ¡ Semiconductor 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 (IO = - 15 m A max.) 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 FEDL6606-03 ¡ Semiconductor MSM6606 BLOCK DIAGRAM SEG1 SEG40 LED1 BLANK 40-DOT SEGMENT DRIVER LED DRIVER TIMING GEN. 40-BIT DATA SELECTOR MON DRIVER -A -B (DATA LATCH A) 41-BIT LATCH (DATA LATCH B) 40-BIT LATCH VDD VSS RESET MODE...
