Advance Information

ROAMING FLEX™ chip SIGNAL PROCESSOR

The FLEX™ protocol is a multi-speed, high-performance protocol adopted by leading service

providers worldwide as a de facto paging standard. The FLEX protocol gives service providers

the increased capacity, added reliability, and enhanced pager battery performance they need

today. It also provides an upward migration path to the service provider that is completely

transparent to the end user.

The MC68181 Roaming FLEX™ chip IC is part of a total solution available from Motorola for

providing FLEX capabilities in a low-power, low-cost system. The FLEX™ chip simplifies

implementation of a FLEX paging device by interfacing with any of several off-the-shelf paging

receivers, and any of several off-the-shelf host microcontroller/ microprocessors. The primary

function of the FLEX™ chip 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 host controls receiver channel selection, and interprets the

message information in an appropriate manner (numeric, alphanumeric, binary, etc.) and

handles all the I/ O activity. The FLEX™ chip IC also 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. Figure 1 shows the MC68181 functional

block diagram.
