3 GENERAL DESCRIPTION
This data sheet describes the operation of the PCD5013
integrated paging decoder. It is fully compatible with other
FLEXchip™ ICs including the PCD5008.
The PCD5013, also referred to as the decoder, simplifies
implementation of a FLEX™ paging device, by being able
to interface with several off-the-shelf paging receivers and
host microcontrollers/processors. Its primary function is to
process information received and demodulated from a
FLEX™ radio paging channel, select messages addressed
to the paging device and communicate the message
information to the host.
The PCD5013 fully supports the FLEX™ protocol
(version G1.9) including all roaming aspects.
Motorola FLEXstack™ software, installed on the product
host processor, communicates with the PCD5013 and
interprets the codewords that are passed to the host.
The PCD5013 operates the paging receiver in an efficient
power consumption mode and enables the host to operate
in a low-power mode when monitoring a single channel for
message information.
