NOTES:

MRF24J40MA

1.0 DEVICE OVERVIEW

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 operates in the

non-licensed 2.4 GHz frequency band and is FCC, IC,

and ETSI compliant. The integrated module design frees

the end user from extensive RF, antenna design, and

regulatory compliance testing and allows quicker time to

market.

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 chip. The module interfaces to

many popular Microchip PIC® microcontrollers via a 4-

wire serial SPI interface, interrupt, wake, reset, power

and ground. The module has an integrated PCB

antenna and matching circuitry all in a compact size.

The MRF24J40MA module is compatible with

Microchip's ZigBee®, MiWi, and MiWi P2P software

stacks. Each software stack is available as a free

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

MRF24J40MA module inside a finished product and not

require testing for an intentional radiator (RF

transmitter). See Section 4.0 “Regulatory Approval”

for specific requirements to be followed by the end user.

This user's guide describes the installation, pin out, and

voltage requirements for optimum operation of the

module. Data communications with the MRF24J40MA

module is 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.

4.0 REGULATORY APPROVAL

The MRF24J40MA module has received regulatory

approvals for modular devices in the United States,

Canada and European countries. Modular approval

allows the end user to place the MRF24J40MA module

inside a finished product and not require testing for an

intentional radiator (RF transmitter) provided no

changes or modifications are made to the module

circuitry. Changes or modifications could void the

user's authority to operate the equipment. The end

user must comply with all of the instructions provided

by the Grantee which indicate installation and/or

operating conditions necessary for compliance.

The end user may still be responsible for testing the

end product for any additional compliance

requirements required with this module installed (for

example: digital device emission, PC peripheral

requirements, etc.) in the specific country that the end

device will be marketed.

Annex F of the IEEE Std. 802.15.4 document has a good

summary of regulatory requirements in various countries

concerning IEEE Std. 802.15.4 devices. The standard
