LED Driver IC

Princeton Technology 

DESCRIPTION

PT6958 is an LED Controller driven on a 1/6 duty

factor. Ten segment output lines, five 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 SOP,

PT6958’s pin assignments and application circuit are

optimized for easy PCB Layout and cost saving

advantages.
