PT6958
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鈥檚 pin assignments and application
circuit are optimized for easy PCB Layout and cost saving advantages.
