PT6964
DESCRIPTION
PT6964 is an LED Controller driven on a 1/7 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 SO
Package, PT6964 pin assignments and application circuit are optimized for easy PCB Layout and cost
saving advantages.
