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 I
2
C-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.
