2
The 83C055, Microcontroller for Television and Video
(MTV) applications, is a derivative of Philips’ industry
standard 80C51 microcontroller.
The 83C055 is intended for use as the central control
mechanism in a television receiver or tuner.

alternative uses)
4 high current open-drain port outputs
12 high voltage (+12 V) open-drain outputs
Programmable video input and output polarities
80C51 instruction set
No external memory capability
Plastic shrink dual in-line package (0.07 inch centre
pins)
High-speed CMOS technology
Power supply: 5 V 10%.
