Description
This FLEXTM Alphanumeric Decoder II date sheet describes the operation of the S5T8702. The S5T8702 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 S5T8702 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.
