DOT MATRIX LCD CONTROLLER WITH 17-DOT COMMON DRIVER AND 80-DOT SEGMENT
DRIVER
GENERAL DESCRIPTION
The MSM6665-xx is a dot-matrix LCD control driver which has functions of displaying charac-
ters, cursor and arbitrators.
The MSM6665-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 MSM6665-01 has standard ROM with 256 different character fonts.
The MSM6665-xx can drive a variety of LCD panels because of the bias voltage, which determines
the LCD driving voltage, can be optionally supplied from the external source.
FEATURES
• Logic supply voltage
: 2.5 to 5.5 V
• LCD driving voltage
: 3.0 to 6.0 V
• Serial interface
• Contains a 17-dot common driver and an 80-dot segment driver
• Contains ROM with character fonts of (5 x 7 dot) x 256
• 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
• 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: MSM6665-01GS-K)
Al pad chip
(Product name: MSM6665-xx)

Notes: 1. Entering commands number 1 to 7 and number 13 does 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 number 5 to 7 and number 13 are set to D0="0".
