LED驅(qū)動(dòng)IC DL8897

DESCRIPTION

DL8897 is an LED Controller driven on a 1/7to 1/8 duty factor. Eleven segment output lines, six grid output lines, 1 segment/grid output lines, one display memory, control circuit , key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for a single chip microcomputer. Serial data is fed to DL8897 via a four-line serial interface. Housed in a 28-pin SO Package, DL8897 pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
