DOT MATRIX LCD CONTROLLER WITH 17-DOT COMMON DRIVER AND 80-DOT SEGMENT
DRIVER
GENERAL DESCRIPTION
The MSM6665C-xx is a dot-matrix LCD control driver which has functions of displaying
characters, cursor and arbitrators.
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.

Data that is input via SI after setting
1 0 1/0 D0="1", is set as data for arbitrator
blink (1-dot unit). This is cancelled by
D0="0"
X 1 X Pointer address is incremented by 1.

blink that is set as all-blank dispalyed
is acceptable, blinking does not occur.

Notes :
1. Commands number 1 to 7 and command number 13 do not affect pointer address.
2. By entering commands number 8 to 12 or display code data, pointer address is
automatically incremented by 1.
3. When Reset is entered, commands numbers 5 to 7 or number 13 are set to D0="0".

Operation
0 0 Operation is canceled. (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.
