SX1212 Transceiver
Ultra-Low Power Integrated 300-510MHz Transceiver
General Description
The SX1212 is a low cost single-chip transceiver
operating in the frequency ranges from 300MHz to
510MHz. The SX1212 is optimized for very low power
consumption (3mA 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 whilst maintaining
design flexibility. 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.

SX1212
This product datasheet contains a detailed description of the SX1212 performance and functionality. Please consult
the Semtech website for the latest updates or errata.
1. General Description
The SX1212 is a single chip FSK and OOK transceiver capable of operation in the 300 to 510MHz license free ISM
frequency bands. It complies with both the relevant European and North American standards, EN 300-220 V2.1.1
(June 2006 release) and FCC Part 15 (10-1-2006 edition). A unique feature of this circuit is its extremely low
current consumption in receiver mode of only 3mA (typ).
The SX1212 comes in a 5x5 mm TQFN-32 package.
