RFM64W
RFM64W ISM TRANSCEIVER MODULE V1.2
General Description
The RFM64W is a low cost transceiver module
operating in the 433MHz frequency bands. The
RFM64W 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. 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 part15.247 and 15.249) regulatory
standards.
In order to better use RFM64W modules, this
specification also involves a large number of the
parameters and functions of its core chip RF64's,
including those IC pins which are not leaded out. All of
these can help customers gain a better understanding of
the performance of RFM64W modules, and enhance the
application skills.

RFM 64W
This product datasheet contains a detailed description of the RFM64W performance and functionality.
1. General Description
The RFM64W is a s FSK and OOK transceiver module capable of operation in the 433MHz 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).
