NJU6624A/B
(3)Combination of NJU6624A(Master) and NJU6624B(slave)
The combination of NJU6624A and B realizes 24character-1line display in 1/8 duty driving.
The instruction sets of version A and B are not so same (refer the instruction table) that the application does not
need to separate the signal lines to MCU.
Therefore, minimum lines (only 5-wires) realize the separately control for version A and B in the combined applica-
tion.
(3-1)A point to notice of master / slave connection
The NJU6624A of master LSI and the B of slave LSI don’t synchronize the frame frequency, so that the timings of
blinking between version A and B are not synchronized.
(3-2)Panel composition of master / slave mode at smooth scroll.
Though the NJU6624A/B generate the space for smooth scroll operation automatically, it does not generate a
space at the right side position by 12th character. Therefore, when the scroll is operated on the 1-line LCD panel
with normal wiring by one driver control, a space after the last character is lacked.
In case of combination application using NJU6624A and B, when the smooth scroll operate on the 1-line LCD, the
data should be set to overlap the memory area which are (0C)H and (0D)H of A and (01)H and (02)H of B, and
SEG1 to SEG5 of NJU6624B should not be wired on the LCD panel for the blank display between the character.
Therefore, the maximum display size is 23-character 1-line in case of this application.
