Display data transferred from the controller (4-bit parallel format) is processed through 80-bit latching and a LCD drive signal is generated. The LC79400D can be used in conjunction with common driver LC7943D (QIP80D) as well as LC79430D (QIP100D) and LC79431D (QIP100D) to drive a wide- screen LCD panel. Package Dimensions unit : mm 3180-QFP100D [LC73701M] Features • On-chip LCD drive circuit (80 bits) • Display duty selection ranging from 1/64 to 1/256 • Supports use of chip disable pin for lower large panel power supply dissipation • Supports externally supplied bias voltage • Operating power supply voltage/operating temperature include VDD (logic block) : 5 V ±10 % / –20 to +75 °C VDD-VEE (LCD block) : 12 V to 32 V / –20 to +75°C • Data transfer clock provides maximum 3.0 MHz and supports bidirectional shift • 4-bit parallel data input • CMOS process • 100-pin flat plastic package Specifications Absolute Maximum Ratings at Ta = 25±2°C, VSS = 0 V SANYO: MFP18 Parameter Symbol Conditions Ratings Maximum supply voltage (logic) VDD max –0.3 to +7.0 Maximum supply voltage (LCD) VDD - VEE max*1 0 to 35 Maximum input voltage VI max –0.3 to VDD + 0.3 Storage temperature range Tstg –40 to +125 Note:1. The voltages V1, V3, V4, V7, VDD and VEE must obey the relationships: VDD ≥ V1 > V3 > V4 > VEE, VDD – V3 ≤ 7V, V4 – VEE ≤ 7V. Unit V V V °C SANYO Electric Co.,Ltd.
