DESCRIPTION

PT6961 is an LED Controller driven on a 1/7 to 1/8 duty factor. 11 segment output lines, 6 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 PT6961 via a four-line serial interface. Housed in a 32-pin SOP, PT6961 pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
