PT6955
DESCRIPTION
PT6955 is an LED Controller driven on a 1/4 to 1/7 duty factor. Twelve/nine segment output lines, 4 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 in a 24-pin SOP, PT6955’s pin assignments and application circuit
are optimized for easy PCB Layout and cost saving advantages.
