FLEX TM ROAMING DECODER II
S5T8701
INTRODUCTION
This FLEXTM Roaming Decoder II date sheet describes the operation of the
S5T8701.
The S5T8701 simplifies implementation of a FLEXTM paging device by interfacing
with any of several off-the-shelf paging receivers and any of several off-the-shelf
host microcontroller/microprocessors. 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 S5T8701 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 signal channel for message information.
32-LQFP-0707
