SSD1702
1. General Description
SSD1702 is a 240-outputs LCD driver capable of both COMMON or SEGMENT driving, selected by
hardware pin setting. It is designed for high resolution dot matrix type LCD panel for the use on PDA or
terminal.
SSD1702 can be used in cascade mode to support display system with more than 240 rows or columns.
In segment mode, 4-bit or 8-bit parallel input modes are available through pin selection.
2. FEATURES
BOTH SEGMENT AND COMMON MODE
Supply voltage for LC driver: +15.0 to +30.0 V
Supply voltage for logic system: +2.4 to +3.6 V
240 outputs for either common or segment driving
Pin selectable between common and segment mode
Low output impedance
Low power consumption
SEGMENT MODE
Maximum XCK clock frequency: 20 MHz (VDD = +3.0 to +3.6V)
15 MHz (VDD = +2.4 to +3.0V)
Pin selectable 4-bit or 8-bit input modes
Automatic transfer function of enable signal
Automatically stop the internal clock after counting 240 bits of input data in chip select mode
Line latch circuit reset function when DISPOFF# active
COMMON MODE
Maximum LP clock frequency: 1 MHz (VDD = +2.4 to 3.6V)
Built-in 240 bits bi-directional shift register
Single (240 bits shift register) or Dual mode (two 120 bits shift register) operations
Shift register circuit reset function when DISPOFF# active
