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)
