frequency 400 kHz).

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 maximum speed independent of the

used crystal frequency.

The P83CL882 is especially suited for low cost analog

cordless telephone applications (CT0, CT1 and CT1+

standards) and wired feature phones. For this purpose,

functions like MSK modem and I2C-bus are integrated

on-chip.

The device is optimized for low-power consumption. It has

two software selectable modes for power reduction: Idle

and Power-down. In addition, the clock to all unused

peripheral blocks can be switched off.

The instruction set is based on that of the 80C51. The

P83CL882 also functions as an arithmetic processor

having facilities for both binary and BCD arithmetic plus

bit-handling capabilities. The instruction set consists of

over 100 instructions: 49 one-byte, 46 two-byte, and

16 three-byte. Port 2 is not incorporated, therefore there is

no external data or memory access and the MOVX

operations cannot be used.
