Product Summary

The M5265 is an LCD driver which can directly drive up to 80 segments in the static display mode and up to 160 segments in the 1/2 duty dynamic display mode. The M5265 is fabricated with low power CMOS metal gate technology. The M5265 consists of a 160-stage shift register, 160-bit data latch, 80 pairs of LCD drivers and a common signal generator. The display data is serially input from the DATA-IN pin to the 160-stage shift register synchronized with the CLOCK pulse. The data is shifted into the 160-bit data latch by the LOAD signal. Then the latched data is directly output to the LCD from the 80 pairs of LCD drivers as a serial output. The common signal can be generated by the built-in generator, or externally input. The common synchronization circuit which is used in the dynamic display mode is integrated on the chip.
