LED Driver IC

Princeton Technology 

DESCRIPTION

PT6964 is an LED Controller driven on a 1/5 to 1/8

duty factor. 10 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 PT6964 via a three-line serial

interface. Housed in a 28 pins SOP Package, PT6964

pin assignments and application circuit are optimized

for easy PCB Layout and cost saving advantages.

APPLICATIONS

• Micro-computer peripheral device

• VCR set

• Combo set
