1.0
The MRF24J40MA is a 2.4 GHz IEEE Std. 802.15.4™
compliant, surface mount module with integrated
crystal, internal voltage regulator, matching circuitry
and PCB antenna. The MRF24J40MA module oper-
ates in the non-licensed 2.4 GHz frequency band and
is FCC, IC and ETSI compliant. The integrated module
design frees the integrator from extensive RF and
antenna design, and regulatory compliance testing,
allowing quicker time to market.

download, including source code, from the Microchip
web site http://www.microchip.com/wireless.
The MRF24J40MA module has received regulatory
approvals for modular devices in the United States
(FCC), Canada (IC) and Europe (ETSI). Modular
approval removes the need for expensive RF and
antenna design and allows the end user to place the

1.1
Figure 1-1 shows a simplified block diagram of the
MRF24J40MA 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 popular Microchip PIC
4-wire serial SPI interface, interrupt, wake, Reset,
power and ground, as shown in Figure 1-2. Table 1-1
provides the pin descriptions.
Data communications with the MRF24J40MA module
are documented in the “MRF24J40 IEEE 802.15.4™
2.4 GHz RF Transceiver Data Sheet” (DS39776). Refer
to the MRF24J40 Data Sheet for specific serial
interface protocol and register definitions.
