SM1211

Ultra Low Power Integrated UHF Transceiver Module

General Description:

The purpose of this module is to provide a development

platform of the SX1211. User can build his application

prototype by simply connecting the module to his target

microcontroller and start developing his application

software. The SM1211 module integrates the SX1211

reference design (chip + external components) plus

miscellaneous useful connectors.

SX1211 is a low cost single-chip transceiver operating

in the frequency ranges from 863-870, 902-928 MHz

and 950-960 MHz. The SX1211 is optimized for very

low power consumption (3 mA in receiver mode). It

incorporates a baseband modem with data rates up to

150 kb/s. Data handling features include a sixty-four

byte FIFO, packet handling, automatic CRC generation

and data whitening. Its highly integrated architecture

allows for minimum external component count while

maintaining design ﬂ exibility.

All major RF communication parameters are

programmable and most of them may be dynamically

set. It complies with European (ETSI EN 300-220

V2.1.1) and North American (FCC part 15.247 and

15.249) regulatory standards.

Note: This module is also used for the SX1211 Starter Kit.
