SED1565 Series
GENERAL DESCRIPTION
The SED1565 Series is a series of single-chip dot matrix
liquid crystal display drivers that can be connected
directly to a microprocessor bus. 8-bit parallel or serial
display data sent from the microprocessor is stored in
the internal display data RAM and the chip generates a
liquid crystal drive signal independent of the
microprocessor. Because the chips in the SED1565
Series contain 65
×
132 bits of display data RAM and
there is a 1-to-1 correspondence between the liquid
crystal panel pixels and the internal RAM bits, these
chips enable displays with a high degree of freedom.
The SED1565 Series chips contain 65 common output
circuits and 132 segment output circuits, so that a single
chip can drive a 65
×
132 dot display (capable of
displaying 8 columns
×
4 rows of a 16
×
16 dot kanji
font). The SED1567 Series chips contain 33 common
output circuits and 132 segment output circuits, so that
a single chip can drive 33
×
132 dot display (capable of
displaying 8 columns
×
2 rows of 16
×
16 dot kanji
fonts). Thanks to the built-in 55 common output circuits
and 132 segment output circuits, the SED1568*
**
is
capable of displaying 55
×
132 dots (11 columns
×
4
lines using 11
×
12 dots Kanji font) with a single chip.
The SED1569 Series chips contain 53 common output
circuits and 132 segment output circuits, so that a single
chip can drive 53
×
132 dot display (capable of displaying
11 columns
×
4 rows of 11
×
12 dot kanji fonts).
Moreover, the capacity of the display can be extended
through the use of master/slave structures between
chips.
The chips are able to minimize power consumption
because no external operating clock is necessary for the
display data RAM read/write operation. Furthermore,
because each chip is equipped internally with a low-
power liquid crystal driver power supply, resistors for
liquid crystal driver power voltage adjustment and a
display clock CR oscillator circuit, the SED1565 Series
chips can be used to create the lowest power display
system with the fewest components for high-
performance portable devices.
