The P8xCL883/P8xCL884 are manufactured in an
advanced CMOS technology. The P8xCL883 is based on
single-chip technology and the P8xCL884 is based on
MCM (Multi-Chip-Module) technology as the EEPROM is
integrated on a separate chip.
The P8xCL883/P8xCL884 are 8-bit microcontrollers
especially suited for low cost analog cordless telephone
applications (CT0, CT1, CT1+ standards). For this
purpose, features like DTMF, EEPROM, MSK modem and
POR/LVD are integrated on-chip.
The device is optimized for low power consumption.
The P8xCL883/P8xCL884 have two software selectable
features for power reduction: Idle and Power-down modes.
In addition, all derivative blocks can switch off their clock if
they are inactive.
The instruction set of the P8xCL883/P8xCL884 is based
on that of the 80C51. The P8xCL883/P8xCL884 also
function 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. Due to the missing port P2, there is no
external data or memory access and the MOVX operations
cannot be used.
This data sheet details the specific properties of the
P8xCL883/P8xCL884; for details of the
P8xCL883/P8xCL884 core and the derivative functions
see the
“TELX family”
data sheet and
