The ST7565S is a single-chip dot matrix LCD driver 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
LCD drive signal independent of the microprocessor.
Because the chips in the ST7565S contain 65x132 bits of
display data RAM and there is a 1-to-1 correspondence
between the LCD panel pixels and the internal RAM bits,
these chips enable displays with a high degree of freedom.
The ST7565S chips contain 65 common output circuits and
132 segment output circuits, so that a single chip can drive a
65x132 dot display (capable of displaying 8 columnsx4 rows
of a 16x16 dot kanji font).
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
LCD driver power supply, resistors for LCD driver power
voltage adjustment and a display clock CR oscillator circuit,
the ST7565S can be used to create the lowest power display
system with the fewest components for high-performance
portable devices.
