GENERAL DESCRIPTION

The P83CL882 is manufactured in an advanced CMOS technology. The P83CL882 is a member of the VTELX family of low-power, low-voltage 80CL51 microcontrollers with advanced features for telecom applications. The Philips exclusive, asynchronous handshaking technology has been used for the CPU implementation which makes the CPU to run at its ma
