7 / 18 page MSM5265 ¡ Semiconductor 7/18 FUNCTIONAL DESCRIPTION Operational Description The MSM5265 consists of a 160-stage shift register, 160-bit data latch, and 80 pairs of LCD drivers. The display data is input from the DATA-IN pin to the 160-stage shift register at the rising edge of the CLOCK pulse and it is shifted to the 160-bit data latch when the LOAD signal is set at "H" level, then it is directly output from the 80 pairs of LCD drivers to the LCD panel. Input the display data in the order of SEG80, SEG79, SEG78, ..., SEG2, SEG1. DATA LATCH Output (inside the IC) 1 23456 159 160 DATA-IN CLOCK LOAD Pin Functional Description • OSC-IN, OSC-OUT, OSC-OUT As shown in the figure below, by connecting the external resistors R0, R1 and external capacitor C0 with OSC-IN, OSC-OUT and OSC-OUT respectively, an oscillating circuit to generate the common signal is formed. This frequency is divided into either 1/8 or 1/4 by the internal dividing circuit. The 1/8 divided frequency is used in the static display mode, while the 1/4 divided frequency is used as the common signal in the 1/2 duty dynamic display mode which is output from the COM- OUT pin. (EXT/INT should be set at low level.) The resistor R1 is used to limit the current on the OSC-IN pin's protecting diodes. The value of the R1 should be more than 10 times that of R0. When the external common signal is used, the EXT/INT pin should be set at high level and the external common signal should be input from the OSC-IN pin. Keep the wiring between the OSC-IN pin and R1 as short as possible, because the OSC-IN pin becomes susceptible to external noise if the value of R1 is large. = R0 R1 OSC-OUT C0 OSC-OUT (MSM5265) OSC-IN fOSC fOSC 1/2.2 C0R0 R1≥10 R0 VDD |
