ST7565S 65 x 132 Dot Matrix LCD Controller/Driver

PublishTime：2022-02-08

●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.
●FEATURES
■▲Direct display of RAM data through the Display Data RAM
■RAM capacity : 65 x 132 = 8580 bits
■Display duty selectable by select pin
1/65 duty : 65 common x 132 segment
1/49 duty : 49 common x 132 segment
1/33 duty : 33 common x 132 segment
1/55 duty : 55 common x 132 segment
1/53 duty : 53 common x 132 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 ReadA/Vrite, Normal/Reverse display 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 =3.0Vt 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
■Wide range of operating temperatures: -40 to 85°C
■CMOS process
■Available Package: Bare chip and TCP
■These chips not designed for resistance to light or resistance to radiation.
