240 Outputs Common / Segment Driver

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.

• 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: 20MHz (VDD = +3.0V to +3.6V)
                                                  15MHZ (VDD = +2.4V 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 = +2.4V 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
