PT6961 Datasheet, PDF (1/18 Pages) Princeton Technology Corp – LED Driver IC

DESCRIPTION
PT6961 is an LED Controller driven on a 1/7 to 1/8
duty factor. 11 segment output lines, 6 grid output
lines, 1 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 PT6961 via a four-line serial
interface. Housed in a 32-pin SOP, PT6961 pin
assignments and application circuit are optimized for
easy PCB Layout and cost saving advantages.
APPLICATIONS
• Micro-computer Peripheral Device
• VCR set
• Combo set
