mode, display ON/OFF, page address set, display start
line set, column address set, status read, display all
points ON/OFF, LCD bias set, electronic volume,
read/modify/write, segment driver direction selects,
power saver, static indicator, common output status
select, V5 voltage regulation internal resistor ratio set.
Static drive circuit equipped internally for indicators.
(1 system, with variable flashing speed.)
Low-power liquid crystal display power supply circuit
equipped internally.
Booster circuit (with Boost ratios of 2X/3X/4X/5X/6X,
where the step-up voltage reference power supply can
be input externally).
High-accuracy voltage adjustment circuit (Thermal
gradient –0.05%/°C ) V5 voltage regulator resistors
equipped internally, V1 to V4 voltage divider resistors
equipped internally, electronic volume function
equipped internally, voltage follower.
CR oscillator circuit equipped internally (external clock
can also be input)
Extremely low power consumption. For example,
operating current with built-in power supply is 60uA
(VDD–VSS = VDD–VSS2 =3.0V, Booster x4, V5–VDD
= –11.0V).
Conditions: When displays pattern OFF and the normal
mode is selected.
Power supply operate on the low 1.8V
Logic power supply
VDD – VSS = 1.8V ~ 3.3V (+10% Range)
Boost reference voltage: VDD – VSS2 = 2.4V to 3.3V
Booster maximum voltage limited
VDD – VOUT= 16.0V (+10% Range)
Liquid crystal drive power supply:
VDD – V5 = 4.0V to 13.0 V

CMOS process
Available Package: Bare chip and TCP
These chips not designed for resistance to light or
resistance to radiation.
GENERAL DESCRIPTION
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.
