1 / 72 page  ST Sitronix ST7565S 65 x 132 Dot Matrix LCD Controller/Driver Ver 0.6c 1/72 2009/09/07 F FE EA AT TU UR RE ES S 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 Read/Write, 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 =3.0V, 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 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. G GE EN NE ER RA AL L D DE ES SC CR RIIP PT TIIO ON N 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.
