is an LED Controller driven to 1/7 duty factor. Twelve/nine segment output lines, to 7 grid output lines, one display memory, control 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 PT6955 via a three-line serial interface. Housed 24-pin SO Package, PT6955's pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
