GENERAL DESCRIPTION
The P8xCx70 family consists of the following devices:
•
P83C270
•
P83C370
•
P83C570
•
P83C770
•
P87C770.
The term P8xCx70 is used throughout this data sheet to
refer to all family members; differences between devices
are highlighted in the text.
The P8xCx70 family of microcontrollers are 8-bit,
80C51-based microcontrollers specifically designed for
the NTSC TV market. Each device has an On-Screen
Display, control functions and Closed Caption that
extracts, decodes (software) and displays caption signals
from NTSC TV signals. Extended Data Service (XDS) is
via the software command interpreter and the V-chip is
also implemented.
