MSM9006-01

E2B0045-27-Y3 ¡ Semiconductor ¡ Semiconductor MSM9006-01, -02 LCD Driver with Keyscan Function This version: Nov. 1997 MSM9006-01, -02 Previous version: Mar.1992 1996 June 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=–15mA max.) Up to five output ports are available (IO=–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) (Product name : MSM9006-02GS-BK) 1/18...
