E2B0008-27-Y2 ¡ Semiconductor ¡ Semiconductor MSM5265 80-DOT LCD DRIVER This version: Nov. 1997 MSM5265 Previous version: Mar. 1996 GENERAL DESCRIPTION The MSM5265 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 MSM5265 is fabricated with low power CMOS metal gate technology. The MSM5265 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. FEATURES Supply voltage : 3.0 to 6.0 V Drives LCD of up to 80 segments (in the static display mode) Drives LCD of up to 160 segments (in the 1/2 duty dynamic display mode) Simple interface with microcomputer Bit-to-bit correspondence between input data and output data H: Display ON L: Display OFF Can be cascade-connected Built-in common signal generator Can be synchronized with the external common signal Testing pins for all-on (SEG-TEST) and all-off (BLANK) Applicable as an o...
