DESCRIPTION

PT6965 is an LED Controller driven on a 1/5 to 1/8 duty factor. 11 segment output lines, 4 grid output lines, 3 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 PT6965 via a four-line serial interface. Housed in a 30-pin SSOP and TSSOP, PT6965 pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
