DESCRIPTION
PT6958 is an LED Controller driven on a 1/6 duty factor. Ten segment output lines, 5 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 PT6958 via a three-line serial interface. Housed in a 28-pin SO Package, PT6958’s pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
