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.
