ST7565R 65 x 132 Dot Matrix LCD Controller/Driver

PublishTime：2022-02-08

●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 theinternal RAM bits, these chips enable displays with a high degree of freedom.
●The ST7565R chips contain 65 common output circuits and 32 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). 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.
