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 SO Package, PT6955’s pin assignments and application circuit are optimized for easy PCB
Layout and cost saving advantages.
