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.
