RFM67W ISM TRANSMITTER MODULE V1.2
Features
GENERAL DESCRIPTION
The RFM67W is a transmitter
module which can operate in the
315, 433, 868 and 915 MHz
licence free ISM bands.
The transmitter module has two
modes of operation, a
conventional MCU controlled
mode and a ‘stand-alone’
mode which enables the

NOTE:
In order to better use RFM67W
modules, this specification also
involves a large number of the
parameters and functions of its
core chip RF67's,including those
IC pins which are not leaded
out. All of these can help
customers gain a better
understanding of the
performance of RFM67W
modules, and enhance the
application skills.

RFM 67W
The RFM67W also includes two timing references; an RC oscillator, for sleep mode operation of the SPI interface (in
MCU mode), and a 32 MHz crystal oscillator, which serves as the low-noise frequency reference of the PLL. The
references and supply voltages are provided by the power distribution system which includes several regulators allowing
true battery powered operation.

4.2.2. MCU Mode
The RFM67W is also capable of operating in a conventional MCU controlled mode. Figure 4 shows the RFM67W
operating in MCU mode and connected to an external microcontroller. Note that CLKOUT provides the oscillator signal
for the MCU, thus negating the need for two crystal oscillators. The DCLK connection is also optional - only being
required if the data rate is to be determined by RFM67W or transmit filtering is to be used.
