SCN0080G_A Datasheet | Avant Electronics

Description .. The SCN0080G_A and the SCN0080G_B are two 80-segment dot-matrix STN LCD drivers. They are designed to be paired with the SCN6400G 64-mon driver. The only difference between the SCN0080G_A and the SCN0080G_B is their pin assignment. The pin assignment of the SCN0080G_B is a mirrored version of the SCN0080G_A. Two types of pin assignments make PCB layout more flexible and increase ponent density. 1.2 Features - 80-output segment driver for dot-matrix STN LCD. - Display duty : 1/8 to 1/128 - Display-OFF function for reducing power consumption. - 4-level external LCD bias voltage. - 4-bit parallel or serial interface with a controller for display data. - Capability of being cascaded in application to expand segment number. - Operating voltage range (control logic): 2.7 ~ 5.5 volts. - Operating voltage range (LCD bias voltage, VDD-VEE): 8 ~ 20 volts. - Data transfer clock: 6.0 MHz, when VDD= 5 volts. - Operating temperature range: -20 to +85 °C. - Storage temperature range: -40 to +125 °C. 1.3 Ordering information Ordering information TYPE NUMBER SCN0080G_A-LQFPG SCN0080G_A-QFPG SCN0080G_A-LQFP SCN0080G_A-QFP SCN0080G_A-D SCN0080G_B-LQFPG SCN0080G_B-QFPG SCN0080G_B-LQFP SCN0080G_B-QFP SCN0080G_B-D QFP100 Green package.
