PT6965 Datasheet, PDF (1/20 Pages) Princeton Technology Corp – LED Driver IC

DESCRIPTION
PT6965 is an LED Controller driven on a 1/5 to 1/8
duty factor. 11 segment output lines, 4 grid output
lines, 3 segment/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 PT6965 via a four-line serial
interface. Housed in a 30-pin SSOP and TSSOP,
PT6965 pin assignments and application circuit are
optimized for easy PCB Layout and cost saving
advantages.
APPLICATIONS
• Micro-computer peripheral device
• VCR set
• Combo set
