SDN8080G Datasheet | Avant Electronics

Description The SDN8080G is a MON/SEGMEMT driver for large-panel dot-matrix STN LCD module. It can be used either as a MON driver or as a SEGMENT driver, by connecting its CS input to VDD or VSS. When its CS input is connected to VDD, the SDN8080G is an 80-MON driver. When its CS input is connected to VSS, the SDN8080G is an 80-SEGMENT driver. 1.2 Features - Operating voltage range (VDD-VSS, control logic): 2.7 ~ 5.5 volts. - LCD bias voltage range (VDD-VEE): 6 ~ 28 volts. - 80-SEGMENT driver or 80-MON driver, via CS-pin selection. - When used as a SEGMENT driver, 4-bit parallel or 1-bit serial interface with a controller. - When used as a MON driver, two modes of operation are available: Single mode or Dual mode. - Display duty cycle: 1/64 ~ 1/256. - LCD on/off control, when used as SEGMENT driver. - External 4-level LCD bias voltage. - Operating frequency range: 8 MHz, when VDD= 5 volts. - Operating temperature range: -30 to +85 °C. - Storage temperature range: -55 to +150 °C. 2005 Sep 29 2 of 40 data sheet (v6) Avant Electronics 2 ORDERING INFORMATION Table 1 Ordering information TYPE NUMBER SDN8080G-LQFPG SDN8080G-QFPG SDN8080G-LQFP SDN8080G-QFP SDN8080G-D SDN8080G 80-outputs mon/segment driver DESCRIPTION LQFP100 Pb-free package.
