MC141511A

MOTOROLA SEMICONDUCTOR TECHNICAL DATA LCD Segment Driver CMOS The MC141511A is an LCD frontplane (segment) driver chip which includes a 656 x 8 display RAM. The MC68HC05L10 microcomputer is the companion device which provides the backplane drive. The MC68HC05L10, together with one MC141511A, may be used to drive a 5248-pixel muxed-by-41 display or a 4096-pixel muxed-by-32 display. Larger displays may be driven by adding additional MC141511A. The MC141511A is a low operating voltage version of MC141511. It is pin to pin compatible to the MC141511. See Application Note AN-HK-13A. Operating Supply Voltage Range Control Logic, RAM, and Latch (VDD Pin): 2.7V to 5.5V Frontplane Drivers (VLCD Pin): 4.5V to 13.2V Operating Temperature Range: -20 to 70˚C Direct Interface with the MC68HC05L10 656 x 8 Static RAM (Display RAM) 128 LCD Segment (Frontplane) Driving Signals 10-Bit Address Bus and 8-Bit Bidirectional Data Bus Selectable 1:32 or 1:41 Multiplex Ratios A...
