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.
