SDN8000G Datasheet | Advanced Semiconductor

Description The SDN8000G is an 80-mon dot-matrix STN LCD driver. It is designed to be paired with the SDN0080G 80-segment driver. 1.2 Features - 80-output mon driver for dot-matrix STN LCD. - Display duty : 1/64 to 1/256 - Power-down mode for reducing power consumption. - External LCD bias voltage. - Capability of being cascaded in application to expand mon number. - Support single mode operation (80-bit shift register) and dual mode operation ( 40-bit x 2 shift register). - In single mode operation, shift direction can be: O1 → O80 or O80 → O1. .. - In dual mode operation, shift direction can be: O1 → O40 and O41 → O80, or O80 → O41 and O40 → O1. - Operating voltage range (control logic): 2.7 ~ 5.5 volts. - Operating voltage range (high voltage, VDD-VEE): 12 ~ 32 volts. - Data transfer clock: 6.0 MHz, when VDD= 5 volts. - Operating temperature range: -20 to +75 °C. - Storage temperature range: -40 to +125 °C. 1.3 Ordering information Ordering information TYPE NUMBER SDN8000G-LQFPG SDN8000G-QFPG SDN8000G-LQFP SDN8000G-QFP SDN8000G-D QFP100 Green package.
