1.0
The MRF24J40MC is a 2.4 GHz IEEE Std. 802.15.4™
compliant, surface mount module with integrated
crystal, internal voltage regulator, matching circuitry,
Power Amplifier (PA), Low Noise Amplifier (LNA) with
50Ω external antenna connector. The MRF24J40MC
module operates in the non-licensed 2.4 GHz
frequency band. The integrated module design frees
the integrator from extensive RF and antenna design,
and regulatory compliance testing allowing quicker
time to market.

Environment software stacks. The MiWi Development
Environment software stack including the source code
is available as a free download, from the Microchip web
site: http://www.microchip.com/wireless.
The MRF24J40MC module has received regulatory
approvals for modular devices in the United States
(FCC) and Canada (IC). Modular approval removes the
need for expensive RF and antenna design, and allows
the end user to place the MRF24J40MC module inside
a finished product and does not require regulatory
testing for an intentional radiator (RF transmitter). To
maintain conformance, refer to module settings in

Preliminary
The MRF24J40MC module has been tested and
conforms to ETS EN 300 328 V1.7.1 (2006-10)
European Standards. The module tests can be applied
toward final product certification and Declaration of
Conformity (DoC). To maintain conformance for
Europe, refer to module settings in

MRF24J40MC module. The module is based on the
Microchip Technology MRF24J40 IEEE 802.15.4™
2.4 GHz RF Transceiver IC. The module interfaces to
many
through a 4-wire SPI interface, interrupt, wake, reset,
power and ground, as shown in
provides the pin descriptions.
