80 SEGMENT DRIVER FOR DOT MATRIX LCD
S6A2067
INTRODUCTION
The S6A2067 is a LCD driver lC which is fabricated by low power CMOS technology. Basically this lC consists of 40 x 2 bit bi-directional shift register, 40 x 2 bit data latch and 40 x 2 bit LCD driver (refer to Figure 1). This lC can be used as segment driver.
FUNCTION
· · Dot matrix LCD driver with 80 channel output. Input / Output signal - Output: 40 x 2 channel waveform for LCD driving - Input: Serial display data and control signal pulse from the controller lC. Bias voltage (V1 to V4)
FEATURES
· · · · Display driving bias: static ~ 1/5 Power supply voltage: 2.7V to 5.5V Supply voltage for display: 3.0V to 13.0V (VLCD = VDD - VEE) Interface Driver (cascade connection) S6A0065, Other S6A2067 · · Controller S6A0069 S6A0070 S6A0073
