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.

Figure 1 : Example Block Diagram Using Internal Demodulator
When configured to use the internal demodulator, the S5T8701 connects to a receiver capable of generating a
limited (i.e. 1-bit digitized) 455kHz or 140kHz IF signal. In this mode, the S5T8701 has 7 receiver control lines
used for warming up and shutting down a receiver in stages. The S5T8701 has the ability to detect a low battery
signal during the receiver control sequences. It interfaces to a host MCU through a standard SPI. It has a 1minute
timer that offers low power support for a time of day function on the host.
When using the internal demodulator, the oscillator frequency (or external clock) must be 160kHz. The CLKOUT
signal can be programmed to be either a 38.4kHz signal created by fractionally dividing the oscillator clock, or a
40kHz signal creating by dividing the oscillator clock by 4.
