PT6958_10 Datasheet, PDF (1/16 Pages) Princeton Technology Corp – LED Driver IC

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.
