ST7533
33 x 96 Dot Matrix LCD Controller/Driver
FEATURES
Direct display of RAM data through the display data
RAM.
RAM capacity : 33 x 96 = 3168 bits
Display duty selectable by select pin
1/33 duty : 33 common x 96 segment
1/17 duty : 17 common x 96 segment
High-speed 8-bit MPU interface (The chip can be
connected directly to the both the 80x86 series MPUs
and the 68000 series MPUs)
/Serial interfaces are supported.
Abundant command functions
Display data Read/Write, display ON/OFF, Normal/
Reverse display mode, 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 select,
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
, where the step-up voltage reference power
supply can be input externally).
High-accuracy voltage adjustment circuit (Thermal
gradient –0.15%/°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 Operating power
when the built-in power supply is used (an example)
70uA (VDD – VSS = VDD – VSS2 =3.0 V, Quad voltage,
V5 – VDD = – 11.0 V).
Conditions: When displays pattern OFF and the
normal mode is selected.
Power supply operate on the low 1.8 voltage
Logic power supply
VDD – VSS = 1.8V to 3.3V (+10% Range)
Boost reference voltage: VDD – VSS2 = 1.8V to 3.3V
Booster maximum voltage limited
VOUT= -13V (+10% Range)
Liquid crystal drive power supply:
VDD – V5 = 4.0V to 13.0 V
Wide range of operating temperatures: –40 to 85°C
CMOS process
These chips not designed for resistance to light or
resistance to radiation.
GENERAL DESCRIPTION
The ST7533 is a single-chip dot matrix LCD 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
LCD drive signal independent of the microprocessor.
Because the chips in the ST7533 contain 33x96 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 ST7533 chips contain 33 common output circuits and 96
segment output circuits, so that a single chip can drive a
33x96 dot display (capable of displaying 8 columnsx4 rows of
www.DataSheet4U.com
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 ST7533 can be used to create the lowest power display
system with the fewest components for high-performance
portable devices.
