S6A0065

40 CH SEGMENT/COMMON DRIVER FOR DOT MATRIX LCD S6A0065 INTRODUCTION The S6A0065 is a LCD driver IC which is fabricated by low power CMOS technology. Basically this IC consists of 20 x 2 bit bi-directional shift register, 20 x 2 bit data latch and 20 x 2 bit driver. (refer to Fig 1) This IC can be used as common or segment driver. FUNCTION Dot matrix LCD driver with 40 channel output. Selects function to use common/segment drivers simultaneously. Input / Output signal - Output: 20 x 2 channel waveform for LCD driving - Input: Serial display data and control signal from the controller LSI. Bias voltage (V1-V6) FEATURES Display driving bias: static - 1/5 Power supply voltage: 2.7- 5.5V Supply voltage for display: 3.0 - 13.0V (VLCD = VDD - VEE) Interface Driver (cascade connection) Other S6A0065, S6A2067 Controller S6A0069 S6A0070 S6A0073 CMOS Process 64QFP or bare chip available 1 S6A0065 40 CH SEGMENT/COMMON DRIVER FOR DOT MATRIX LCD BLOCK DIAGRAM Part 1 SC1 SC2 SC19 SC20 Part 2 SC21 SC22 SC39 SC40 V1 V2 V3 V4 V1 LCD DRIVER V2 LCD DRIVER V5 V6 VDD Data Latch (20 bits) Bidirectional Shift Register (20 bits) Data Latch (20 bits) Bidirectional Shift Register (20 bits) VSS VEE M CL1 CL2 SW CONTR Logic FCS DL1 SHL1 DR1 DL2 SHL2 DR2 Figure 1.
