GENERAL DESCRIPTION
The term P83CL78x is used throughout this data sheet to
refer to both the P83CL781 and P83CL782; differences
between the devices are highlighted in the text.
The P83CL78x is manufactured in an advanced CMOS
technology. The P83CL78x has the same instruction set
as the 80C51, consisting of over 100 instructions:
49 one-byte, 46 two-byte, and 16 three-byte. The device
has low power consumption and a wide range of supply
voltage; there are two software-selectable modes of
reduced activity for further power reduction: Idle and
Power-down. For emulation purposes, the P85CL781
(piggy-back version) with 256 bytes of RAM is
recommended.
The P83CL782 is a faster version of the P83CL781 and
operates at a maximum frequency of 12 MHz at
V
DD
≥
3.1 V.
This data sheet details the specific properties of the
P83CL78x. For details of the 80C51 core and the I

APPLICATIONS
The P83CL78x is an 8-bit general purpose microcontroller
especially suited for cordless telephone applications.
The P83CL78x also functions as an arithmetic processor
having facilities for both binary and BCD arithmetic plus
bit-handling capabilities.
