2 GENERAL DESCRIPTION
The P87CL881 is an 8-bit microcontroller especially suited
for pager applications.
The P87CL881 is manufactured in an advanced CMOS
technology and is based on single chip technology.
The device is optimized for low power consumption and
has two software selectable features for power reduction:
Idle and Power-down modes. In addition, all derivative
blocks switch off their clock if they are inactive.
The instruction set of the P87CL881 is based on that of
the 80C51. The P87CL881 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.
This data sheet details the specific properties of the
P87CL881; for details of the P87CL881 core and the
derivative functions see the “TELX family” data sheet and
“8051-Based 8-bit Microcontrollers; Data Handbook IC20”.
