Detailed functional description

The S2-LP integrates a configurable baseband modem with proprietary fully programmable

packet format allowing also:



IEEE 802.15.4g applications



The hardware packet supports whitening, CRC, FEC and dual SYNC word

detection.



Wireless M-Bus applications

In order to reduce the overall system power consumption and increase the communication

reliability, the S2-LP provides an embedded programmable automatic packet

acknowledgment, automatic packet retransmission, CSMA/CA engine, low duty cycle

protocol, RX sniff mode and timeout protocol.

The S2-LP fully supports antenna diversity with an integrated antenna switching control

algorithm.

Transmitted/received data bytes are buffered in two different 128 bytes FIFOs (TX FIFO

and RX FIFO), accessible via SPI interface for host processing.

In addition, the reduced number of external components enables a cost effective solution

permitting a compact PCB footprint.

The S2-LP targets volume applications like:



sensors to Cloud



smart metering



home energy management systems



wireless alarm systems



smart home



building automation



industrial monitoring and control
