The term P8x Cx70 is used throughout this data sheet to refer to all family members; differences between devices are highlighted in the text. The P8x Cx70 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)...
