MRF24WN0MA/MB
1.0 DEVICE OVERVIEW
The MRF24WN0MA and MRF24WN0MB are low-
power, 2.4 GHz, IEEE 802.11n compliant, surface
mount modules containing all associated RF
components: crystal oscillator, bypass and bias
passives with integrated MAC, baseband, RF and
power amplifier, and built-in hardware support for
encryption. Refer to Figure 1-1.
The integrated module design frees the designer from
RF and antenna design tasks and regulatory
compliance testing, ultimately providing faster time to
market.
The MRF24WN0MA/MB modules are designed to be
used with Microchip's MPLAB® Harmony Integrated
Software Framework. The integrated framework imple-
ments the Application Programming Interface (API)
that is used for command and control, management
and data packet traffic.
The MPLAB Harmony basic framework is available via
a free download from the Microchip web site at
http://www.microchip.com/harmony. For more informa-
tion on the basic framework and available release ver-
sions, refer to “MPLAB® Harmony Release Notes and
Contents” found under the Documentation tab.
The MRF24WN0MA module is approved for use with
the integrated PCB trace antenna. The MRF24WN0MB
module is approved for use with specific external
antenna types that are certified with the module. An
ultra-small coaxial connector (W.FL) is provided on the
module for connection to the external antenna. Refer to
Section 3.3, "External Antenna Types" for a listing of
approved antenna types.
The MRF24WN0MA/MB modules received the regula-
tory approvals for modular devices in the United States
(FCC) and Canada (IC). Modular approval removes the
need for expensive RF and antenna design, and
enables the end user to place the MRF24WN0MA/MB
modules inside a finished product without requiring a
regulatory testing for an intentional radiator (RF trans-
mitter).
The MRF24WN0MA/MB module is an R&TTE Directive
assessed radio module for operation in Europe. The
module tests can be applied toward final product
certification and Declaration of Conformity (DoC).

MRF24WN0MA/MB
2.0 CIRCUIT DESCRIPTION
2.1 Overview
The MRF24WN0MA/MB module interfaces to the
PIC32 MCU via a 4-wire SPI port, Interrupt and Hiber-
nate pins as illustrated in Figure 2-1. The
MRF24WN0MA/MB modules are designed to work
with Microchip's MPLAB® Harmony Integrated Soft-
ware Framework. The integrated framework imple-
ments the Application Programming Interface (API)
that is used for command and control, management
and data packet traffic.
The MPLAB Harmony basic framework is available via
a free download from the Microchip web site at
http://www.microchip.com/harmony. For more informa-
tion on the basic framework and available release ver-
sions, refer to the “MPLAB Harmony Release Notes
and Contents” found under the Documentation tab.
If you are new to the MPLAB Harmony framework, visit
http://www.microchip.com/harmony and go to the
Training > Getting Started tab.
The MPLAB Harmony Help document is available for
download from the MPLAB Harmony framework direc-
tory: c:\microchip\harmony\<version>\doc.
The PIC32 input/output ports (SPI, Interrupt and Hiber-
nate) are configured in the MPLAB Harmony frame-
work configuration files as described in the MPLAB
Harmony Help document.
2.2 MODE0 and MODE1 Pins
The MODE pins must be tied to the voltage levels for
normal operation of the module. Refer to Table 2-1.
The MODE pins are sampled at power on and wake-
up. Refer to Section 2.6, "Hibernate". In the case of
SPI_CS/MODE1 pin, pull-up using a 10 k resistor and
the host MCU allows an active-high signal during
power on and wake-up to ensure that the module start-
up in normal operation. Once the module is
operational, the pin becomes the SPI Port Chip Select
pin (active-low).

2.4 Interrupt Pin
The SPI_INT line works in conjunction with the SPI
port. It is an active-low output signal to the host MCU to
signal an interrupt event.
2.5 VDD and GND Pin
The MRF24WN0MA/MB wireless module contains an
integrated power management unit that generates all
necessary voltages required by the internal circuitry.
The module is powered from a single voltage source.
Table 2-3 lists the recommended bypass capacitors.
The capacitors must be closely placed to the module.
2.6 Hibernate
The module enters the lowest power mode when the
HIBERNATE pin is asserted low. No state information
is preserved. The MPLAB Harmony framework can
save state information in the host MCU that can be
restored after wake-up (HIBERNATE pin is asserted
high).
The module can wake-up when HIBERNATE pin is
asserted high. The module must be initialized and any
state information saved prior to Hibernate state is
restored. This process approximately takes 40 ms.

3.2 Integral PCB Trace Antenna
For the MRF24WN0MA, the PCB antenna is fabricated
on the top copper layer and covered in solder mask.
The layers below the antenna do not have copper
trace.
It is recommended that the module is mounted on the
edge of the host PCB. It is permitted for PCB material
to be below the antenna structure of the module as long
as no copper traces or planes are on the host PCB in
that area. For best performance, place the module on
the host PCB according to the details shown in
Figure 1-6.
The antenna patterns plotted in Figure 3-2 through
Figure 3-5 are the simulated results of the PCB
antenna.
Figure 3-2 illustrates the simulation drawing. The two-
dimensional (2D) radiation pattern is illustrated in
Figure 3-3, whereas Figure 3-4 and Figure 3-5 shows
the three-dimensional (3D) radiation patterns.
The calculated average of the radiated field is shown in
Figure 3-3. The radiation pattern for the XZ plane is
shown in red, whereas the YZ plane is shown in violet.
The most powerful radiation occurs in the XZ plane as
represented by the red pattern.
Figure 3-4 shows the relative position of the 3D radia-
tion “donut” with reference to the module orientation.
This is a very useful guide for placement of the module
to obtain the maximum range.
Figure 3-5 shows the 3D radiation pattern with the col-
ored distribution of the radiation magnitude. The values
range from -9 dB to +0.3 dB. This is very useful in inter-
preting the 2D radiation pattern.
