The MSM6665C-xx is provided with a 17-dot common driver, 80-dot segment driver, display RAM and character ROM, and is controlled with the commands from the serial interface. The character ROM can change the font data by mask option. The MSM6665C-02 has standard ROM with 256 different character fonts. The MSM6665C-xx can drive a variety of LCD panels because the bias voltage, which determines the LCD driving voltage, can be optionally supplied from the external source. FEATURES • Serial interface • Contains a 17-dot common driver and an 80-dot segment driver. • Contains ROM with character fonts of (5 x 7 dots) x 256. • A built-in RC oscillator circuit. • Provided with 80-dot arbitrators. • Switchable between 1/9 duty (1 line; characters + cursor + arbitrator) and 1/17 duty (2 lines; characters + cursor, 1 line; arbitrator). • Character blink operation can be switched between all-characters lighting-on mode and all- characters lighting-off mode. • SiG C-MOS process • Arbitrator blink operation can be switched between 5-dot unit mode and 1-dot unit mode. • Package options : 128-pin plastic QFP (QFP128-P-1420-0.50-K) (Product name: MSM6665C-xxGS-K) Aluminum pad chip (Product name: MSM6665C-xx) xx indicates code number. 1/31 ¡ Semiconductor AC Characteristics Parameter CS Setup Time CS Hold Time SO ON Delay Time SO OFF Delay Time SO Output Delay Time Input Setup Time Input Hold Time Input Waveform Rise Time, Fall Time Reset Pulse Input Pulse Width Symbol tCS tCH tON tOFF tDLY tIS tIH tr, tf tRT Condition — — — — CL=45pF — — All inputs — FEDL6665C-02 MSM6665C-xx (VDD=2.5 to 5.5V, Ta=–40 to +85°C) Min.

The "address" is a number between 0 and 2FH, given by A0 through A5 in hexadecimal. When addresses 30H through 3FH are specified, display data and CHB, CSC, CSB, CCB commands become invalid through an address pointer is set up. Normally, the address pointer is a loop of 0H through 2FH. • LOT (Load Option) [1,0,1,1,X,X,I1,I0] This command indicates some specific operation of display at the current address which is performed each time of AINC command execution. Operation is specified by bit I1 and I0 of the command. I1 I0 Operation 0 0 Operation is cancelled. (No operation) 0 1 Hereafter, equivalent to writing blank code at each AINC execution. 1 0 Hereafter, Cursor-off and blink-cancellation are executed at each AINC execution. 1 1 Both of above two operations are made. Note: When blink-cancellation is executed, all RAM data, which controls blinks for each bit of the arbitrator, go zeros. • BKCG 1/0 (Bank Change 1/0) [1,0,0,X,0,0,0,1/0] Command used to do switching between display address groups (switching between BANKs), which is valid only when 1/9duty display is selected. When D0 is "0", display address range becomes 0 through 15, and 32 through 47. When D0 is "1", display address range becomes 16 through 31, and 32 through 47. Command execution and display data setting are not affected by Bank setting. The D0 status is not changed by Reset inputting. The D0 status is unknown when the system is powered on. So D0 must be set to "0" or "1" with the command. • SOE/D (Serial Out Enable/Disable) [1,0,0,X,0,1,1,1/0] Command used to control the impedance of SO output pin. When D0 is "1", display data is output via SO pin. When D0 is "0", SO pin goes to high impedance. The D0 status is not changed by Reset inputting. The D0 status is unknown when the system is powered on. So D0 must be set to "0" or "1" with the command. 12/31 12 Page
