DEVICE OVERVIEW
1.1
Interface Description
The MRF24J40MB is a 2.4 GHz IEEE Std. 802.15.4?
compliant, surface mount module with integrated
crystal, internal voltage regulator, matching circuitry,
Power Amplifier, Low Noise Amplifier and PCB
antenna. The MRF24J40MB 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.
The MRF24J40MB 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 MRF24J40MB 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
MRF24J40MB module inside a finished product and
not require regulatory testing for an intentional radiator
(RF transmitter).
Figure 1-1 shows a simplified block diagram of the
MRF24J40MB 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 ? microcontrollers via a
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 MRF24J40MB 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.
Note:
See Section 3.0 “Regulatory Approval”
for specific requirements to be followed by
the integrator.
