MC68181 ROAMING FLEX chip IC

Roaming FLEX protocol is a multi-channel, multi-speed, high-performance protocol adopted by leading service providers worldwide as a de-facto roaming paging standard. Roaming FLEX protocol gives service providers the increased capacity, added reliability, and enhanced pager battery performance needed today, coupled with the ability to control a PLL synthesized receiver to receive paging messages from a list of paging channels. 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 Roaming FLEX capabilities in a low-power, low-cost system. The Roaming FLEX chip simplifies implementation of a Roaming FLEX paging device by interfacing with many standard paging receivers, and host microcontroller/microprocessors. The primary function of the Roaming FLEX chip is to process information received and demodulated from a radio paging channel, select messages addressed to the paging device, and communicate the message.

A information to the host. The host interprets the message information in an appropriate manner (numeric, alphanumeric, binary, etc.) and handles all the I/O activity. The Roaming 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 message information for the paging device is not IN being received.
