PCF8577 PCF8577A
LCD DIRECTIDUPLEX DRIVER WITH 12C-BUS INTERFACE
GENERAL DESCRIPTION
The PCF8577 is a single chip, silicon gate CMOS circuit. It is designed to drive liquid crystal displays with up to 32 segments directly, or 64 segments in a duplex manner. The two-line 12 Cbus interface substantially reduces wiring overheads in remote display applications. Bus traffic is minimized in multiple IC applications by automatic address incrementing, hardware subaddressing and display memory switching (direct drive mode). The PCF8577 and PCF8577 A differ only in their slave...
