FAQ

ST7565R

65 x 132 Dot Matrix LCD Controller/Driver

Product Description

The ST7565R is a single-chip dot matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or 4-line SPI 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 ST7565R 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 ST7565R 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 columns x4 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 ST7565R 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 6800 series MPUs)/4-line SPI 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 selects, power saver, static indicator, common output status select, Vo voltage regulation internal resistor ratio set.

•Static drive circuit equipped internally for indicators.

(1 system, with variable flashing speed.)

•Embedded analog power supply circuits for Liquid Crystal driving: Booster, Regulator and Follower.

•Embedded Booster circuit:

- Add new booster ratio, 5 times and 6 times. So that 2X,3X,4X,5X,6X are supported.

- The independent input for boost reference voltage.

•High-accuracy Regulator circuit:

Build-in Electronic volume function for the contrast control. Thermal gradient = – 0.05%/° C.

•Embedded voltage Follower circuit for LCD driving.

•Embedded R-C oscillator circuit.

- The external clock is also supported.

•Extremely low power consumption: 60uA, bare dice (using the internal power).

Settings:VDD – VSS = VDD2 – VSS =3.0 V, Booster Ratio=4,

V0 – VSS = 11.0 V. Display OFF and the normal mode is selected.

•Logic power supply : VDD – VSS = 1.8V to 3.3 V

Analog Power (Boost reference voltage):

VDD2 – VSS = 2.4V to 3.3V

Booster maximum voltage limited

VOUT= 13.5V

Liquid crystal drive power supply:

V0 – VSS = 3.0V to 12.0 V

•Wide range of operating temperatures: – 30 to 85°C

•Package type: COG only.

•The chip is not designed to resist the light or to resist the radiation.
