General Description
Features and Benefits
● Evaluates the MAX4147X Sub-1GHz ISM Receiver
The MAX4147X evaluation kit (EV kit) contains a single
MAX4147X high output power VHF/UHF sub-GHz ISM/
SRD receiver designed to receive frequency-shift keying
(FSK), Gaussian GFSK, or amplitude-shift keying (ASK)
data in the 287MHz to 320MHz, 425MHz to 480MHz, and
860MHz to 960MHz frequency ranges.
● Single Input Voltage Supply from 1.8V to 3.6V
®
● Direct Interface with a MAX32630FTHR Arm
Microcontroller (MCU) Board
● Available PMOD Hardware Interface
● Windows 10-Compatible Software
The MAX41470, MAX41473, and MAX41474 EV kits oper-
ate in conjunction with an external microcontroller (MCU)
and graphical user interface (GUI) software running on
a computer. The MAX41470 uses an SPI interface for
internal register configurations while the MAX41473/74
● On-Board SPI Interface Control for the MAX41470

can use the preset modes or an I C interface for register
● Proven Four-Layer PCB Design
● Fully Assembled and Tested
programming and control.
The MAX41473 and MAX41474 EV kits are also designed
to operate with a simple, one-pin data interface, alleviat-
ing the need to program the part for nominal operation,
or other high-level system (PC with GUI software) hav-
ing to configure the receiver for operation. These parts
allow the user to preset the operating frequencies by
part selection and pin configurations. On the EV kit,
selecting the frequency of operation is as simple as
setting jumpers.

Power
MAX4147X EV Kit Printed Circuit Board
The MAX4147X EV kit board can be powered directly from
the FTHR board PMIC through the H1 header, directly from
the supply test points, or through the user-installed PMOD
header. A single +1.8V to +3.6V, 20mA power supply can be
connected to the board using the two wire loops (marked
3V NOM and GND) when JU5 is not populated. Jumper
JU5 selects the source of power when not using the direct
connection test points: from the L3OUT of the FTHR board
or the PMOD_VDD of the PMOD connector.
The MAX4147X EV kit PCB is manufactured on a 4-layer,
1oz copper, FR4 dielectric stack-up PCB. The board was
designed to accommodate all three versions of the ISM
receiver: MAX41470, MAX41473 and MAX41474. The
board was designed to accommodate the MAX41470
and other members of the MAX4147X family with the
use of resistors and jumpers. Layer 1 is used to route the
receiver and oscillator signals. Layer 2 is a ground layer.
Layers 3 and 4 are used to route the jumper connections

470Ω recommended) to provide visual feedback of the
activity on the supply, DATA and RSSI lines. Populating
these LEDs and resistors will cause additional power con-
sumption and they are not included by default in the EV kit
assembly.
I C Pull-Ups
Resistors R8 and R9 along with jumper JU3 have been
provided as on-board pull-ups which are required for proper
2
I C interfacing and termination. These pins are open-collec-
tor (or open-drain) outputs from the MCU and need to have
pull-up resistors to operate properly. Two 4.7kΩ resistors
are pre-populated on the MAX4147XEVKIT and can be
connected to the positive supply by shorting the JU3 jumper
1-2 and 3-4. This should only be connected when the I2C/
PRESET pin is connected to logic high, thus selecting the
PMOD Interface
The MAX4147X EV kit provides a PMOD-compatible
header footprint to interface with the transmitter. The JU4
connector can be populated with a 6-pin, 100mil, right-angle
header allowing direct connections to the CSB, RSSI, SCL,
SCLK_SDA, ground, and VDD lines, making it compatible
2
I C interface mode of the MAX41473/74. It should be noted
2
that the FTHR board also has footprints for I C pull-up
resistors at R6 and R11. Both sets of pull-up resistors (on
the FTHR board and the MAX4147XEVKIT) should not be
populated simultaneously, otherwise incorrect I C signal
levels may result. Refer to Appendix II for detailed informa-
tion on Evaluation Kit Hardware Modifications.

with either SPI or I C PMOD interfacing. Populating this
header would allow control from the MAX32600MBED kit
and the MAXREFDES72# Arduino Uno R3 to PMOD shield
adaptor. When using the PMOD interface to supply the
MAX4147X EV kit with power, make sure to connect the
JU5 jumper between pins 2-3. See Appendix II for detailed
information on EV kit hardware modifications.

Detailed Description of Software
The MAX4147X EV kit controller GUI software is designed to control the MAX4147X EV kit board and the MAX32630FTHR
2
board, as shown in Figure 17. The software includes USB controls, which provide SPI, I C, and power to the MAX4147X
through the FTHR board interface.

Comport
Encoding
The Comport section provides a drop-down list of seri-
al communication ports available for connection to a
MAX4147X EV kit through a FTHR board. When the GUI
is run after connecting the EV kit hardware, the drop-down
list should default to the proper COM port. If the hardware
is connected to the computer after the GUI is started, click
on the Refresh button to scan for compatible ports. Once
the appropriate COM port is selected in the drop-down list,
click on the Connect button. (See Figure 7.)
The Encoding section allows the user to define the
type of data being transmitted. The two options here are
Manchester or NRZ and are available in the drop-down
list. (See Figure 14.)
Crystal Oscillator
The Crystal Oscillator section allows the user to match
the GUI calculation to the frequency of the crystal installed
on the MAX4147X EV kit (f ). All EV kits come prepop-
XTAL
ulated with a 16.000MHz crystal, and the default setting
in the GUI is assumed to be 16.0MHz. This value can be
adjusted to 12.8MHz or 19.2MHz and will be used when
programming frequency-based registers that are depen-
After properly connecting to the COM port with the FTHR

XTAL
To change the reference oscillator, select the oscillator
frequency in the drop-down list. (See Figure 14.)
Voltage (1.8V to 3.3V)
The Voltage section provides a user-adjustable power
supply from the FTHR board MAX14690N power man-
agement IC (PMIC) to the MAX4147X EV kit and can be
used as the primary VDD supply. The PMIC L3OUT can
be set to voltages between 1.8V to 3.3V and it applies to
the level of the logic interface lines as well as the device
supply. (See Figure 9.)
Center Frequency
The Center Freq section is used to set the carrier or
“center” frequency of the MAX4147X (f or f ). The
value entered in this section will be used to calculate
the three-word fractional-N value programmed into the
LO_CTR_FREQ3 (0x09), LO_CTR_FREQ2 (0x0A), and
LO_CTR_FREQ1 (0x0B) registers. The GUI will calculate
the values for the PLL registers using the crystal frequency
and the following formula:

are selected).
To select the receiver, chose the appropriate part in the
Device Type drop-down list and click on the Set button.
(See Figure 10.)
Receiver Bandwidth
The channel filter bandwidth programmed into the device
is selected using the Receiver Bandwidth drop-down list.
The population of this list is dependent on the IF frequency
selected. The options correspond to those listed in register
IF_CHF_SEL (0x002). When 200kHz IF is selected, the
options are 170kHz, 60kHz, 26kHz, 12kHz, or 6kHz. If
400kHz IF is selected, the options are 340kHz, 120kHz,
52kHz, 24kHz, or 12kHz. Through the drop-down list, the
desired channel filter bandwidth (CHF) is selected for con-
figuration in the device. (See Figure 14.)
Modulation
The Modulation section allows the user to set the
form of modulation for the MAX4147X device. When a
MAX41473 is selected, only ASK modulation will be avail-
able in the drop-down box. Similarly, when MAX41474 is
selected, only FSK will be available in the drop-down box.
To select the modulation, chose ASK or FSK in the
Modulation drop-down list. (See Figure 14.)

Nominal FSK Deviation
Polling – WUT Duration
This is only valid when the modulation selected is FSK.
When FSK is selected, the Nominal FSK Deviation value
will be available through the drop-down list. The available
ranges in the drop-down list are based on the configura-
tion factors already defined to include the IF frequency and
the channel filter bandwidth. This will impact the DEMOD_
FSK setting in the DEMOD register (0x00).
The WUT Duration is a configurable duration that defines
the time the receiver is in the PollingRX state. This is
programmable between 0.48ms and 20.88ms. This pro-
grammed value is only used when in Polling mode and will
not impact the SlaveRX state.
Polling – WUT Duty Cycle
The WUT Duty Cycle defines the duty cycle of the detec-
tion duration versus the wait time. See the device data-
sheet for Wake-Up Timer in Self-Polling Mode diagram for
more details. The ratio is programmed in the WUT2 (0x18)
register where:

As shown in Figure 18, a Manchester 2kbps signal could
look like a 2kHz square wave to represent all 1’s (or all 0’s
if shifted in phase) in Manchester encoded data. And an
NRZ 4kbps signal could look like a 2kHz square wave to
represent alternating 0’s and 1’s.

Polling – Preamble Word
The Preamble Word is the Manchester encoded word
that is compared against the incoming data stream. When
the word is detected, the PREAMB_DET bit is set in the
ISR register and the DATA line, which is held high during
the PollingRX state, will transition from high to low. This
is the interrupt for the microcontroller. It is important to
note that the preamble word is Manchester encoded. This
means that a standard square wave into the device as
the preamble would require that the preamble word be
programmed with 0x0000 or 0xFFFF (depending on the
length desired for the preamble word, as defined in the
PREAMBLE_CFG1 register through the PREAM_LEN
bits). After entering the desired value in the Preamble
Word field, click the Set button. The GUI detects the num-
ber of nibbles through the entry in the Preamble Word
field and will program the PREAMB_LEN based on this
entry.
Intention of Polling
Polling allows the system to go into a lower-power state
until the receiver and microcontroller are awakened for
active receiving of the signal. The microcontroller can be
in a pause or sleep state until the MAX4147X detects the
preamble word. When the word is detected, the interrupt
from the MAX4147X goes to the microcontroller to wake
it up for ‘listening’. The DATA line during the PollingRX
state is kept high. At the time of the detection, the DATA
line will transition low as the interrupt. The microcontroller
acknowledges the interrupt by reading the ISR (0x13)
register. If the PREAM_DET bit is set in the ISR register,
then the microcontroller places the MAX4147X into the
SlaveRX state through the STATE_CTRL1 register, the
same register used to place the device into the PollingRX
state (SLAVE_RX_EN bit versus the WUT_EN bit). When
in the SlaveRX state, the WUT Duration, WUT Duty Cycle,
and Preamble Word do not impact the operation. These
are only used in the PollingRX state.

Action Buttons – Write Registers
Action Buttons – PollingRX
The Write Registers button will take the combination
of all the settings within the GUI and write the registers
accordingly. Many of the settings within the MAX4147X
are dependent on multiple bit settings within the device.
This button will combine all settings to determine the reg-
ister writes required.
The PollingRX button will be active once the registers
are programmed, either through the Write Registers
button or the Load Config button. This button will place
the device into PollingRX mode for preamble detection.
When the preamble is detected, the microcontroller will
automatically respond appropriately as described above
and place the device into SlaveRX mode.

display the data received. Since the configuration regis-
ters should not be programmed in any active state, the
GUI will grey out the other buttons and settings during
the SlaveRX state. The RX State status will move to the
Slave Receiver state. To exit the SlaveRX state, click the
SlaveRX button again.
The Time Plot button allows the user to visually see
the DATA pin displayed in a plot. This plot works best at
around the 10kbps rate and lower for proper oversam-
pling of the received signal.
The StartRF buttons should be clicked to begin the dis-

the top of the block, a header displays the name of the
selected register (eg “STATE_CTRL1”), the “Index” or
address of the register in both decimal (“0d”) and hexa-
decimal (“0000h”) form.
.xml File
The register descriptions for the MAX4147X GUI are
available in an .xml file which is stored with the executable
in the application directory. The default file loaded when
the GUI is initialized is MAX4147X_Registers.XML.
This file can be edited as needed to adjust the names of
fields, provide simple indicators to the GUI user, or allow
for flexible updates to the GUI interface in the future.
The body of this section shows a table with the names of
the individual bits for the selected 8b register along with
the current value programmed into each bit or bit group.
The remaining portion of the body shows a table with the
bit indexes, the type of register (write/read), the name of
the bit or bit group, the Reset value, and a description of
the bit or bit group.
Use Cases
Two Interface Modes for
Data Transmission and Control
Read and Write Registers
The MAX4147X allows a great deal of flexibility when it
comes to receiving data. Typically, the fewer pins used to
interface with the device, the simpler it is to control and
transmit data.
Most of the registers in the MAX4147X are both readable
and writable. The read-only registers are RSSI (0x10),
FEI (0x11), PDF_OUT (0x12), ISR (0x13), STATE_CTRL2
(0x15), PART_NUM (0x1E), and REV_NUM (0x1F).
Writing values to a register can be accomplished by
selecting the register of interest, typing a Hex or Dec
value into the Value field, and clicking on the Write
Register X button (where X is the decimal address of the
register). Reading the register content is similar: select
the register of interest and click on the Read Register X
button.
Preset Mode
Preset mode is the simplest interface of the three options.
It relies on the part number to choose the modulation
(MAX41473 for ASK; MAX41474 for FSK) and jumper
settings (or tri-level pin connections) to configure the part
for a defined carrier frequency (See Tables 4 and 5). With
the Preset mode, the data rate and frequency deviation,
in the case of FSK modulation, need to be within expected
ranges for proper operation.
Register Bit Field
Individual bits or bit groups can be programmed without
having to enter the full value of the register. To program
a bit or group of bits, first select the register of interest
(WUT2, 0x18 for example), next select the bit or bit group
to be changed (TSBY_TDET_RATIO as an example),
enter the binary code for the new value (0000011b), and
hit Enter—the new value will automatically be reflected in
the Value field and will be written to the device.

I C Mode

The I C interface mode allows the user to access the
internal registers of the MAX41473/74 devices, permitting
full control over the receive frequency, data rate, thresh-
olds, bandwidths, etc.
This mode only requires two digital pins to interface with
the transmitter but has a more complicated, packet-based
protocol for interacting with the device. Once configured

SCL facilitate bidirectional communication between the

permit data transfer. The MAX41473/74 functions as an

gramed to power-down into one of three low-current,
non-receiving states after completing a transmission:
Shutdown, Sleep, and Standby modes.
Shutdown is the lowest-current power-down state and is
the default condition for all devices. No programming of
the device can happen in the Shutdown state, and any
previous programming is lost. Sleep allows the interface
to be awake, but without the internal clocks running.
Standby allows the receiver to start up quicker than
shutdown by keeping the crystal oscillator circuit running.
Standby is the proper state to configure the device for
operation.
2
All the MAX41473/74 devices are identified with an I C
address of 0xD6 for write and 0xD7 for read sequences.
Packet transmission is described in the various device
2
datasheets within the “Two-Wire I C Serial Interface”
section.
SPI Mode
To set the power-down state, drive the PWRDN pin high.
To transition to Sleep state, drive the PWRDN pin low.
To transition to the Standby state, program the STATE_
CTRL1 (0x14) EN_XO bit to a 1b.
The SPI interface is only available on the MAX41470
device. Similar to the I C devices, the SPI interface allows
access to the internal registers of the receiver. This per-
mits the user to have full control over the same proper-
ties of over the receive frequency, data rate, thresholds,
bandwidths, etc.

2) Connect the MAX32630FTHR to a power source.
a. Use a USB Micro-B cable to connect the MAX32630FTHR board to a suitable power source (no USB connectivity
is required). Alternatively, you can power the board from a charged battery as long as you remember to turn it on
by pressing the power/reset button next to the battery connector. The board turns on automatically when powered
from the USB supply.
b. The status LED on the FTHR board should be lit a steady red.
3) Connect the MAX32625PICO to a PC.
a. Use a USB Micro-B cable to connect the HDK to a PC, through the connector marked HDK (The white USB cable
in the photos).
b. The status LED on the DAPLINK board will blink red when connecting.
c. After a few seconds of activity, the PC will recognize the DAPLINK as a standard USB drive.
4) Drag-and-drop or save a the ism_radios_fw.bin program binary to the mbed or DAPLINK USB drive.

a. The FTHR board LED will shut off and the LED on the MAX32625PICO will slowly flash red as the FTHR board
is being programmed.
b. Once the programming is complete, the DAPLINK USB drive will disconnect from the PC and reconnect as a
USB drive again.
c. If the programming was successful, the contents of the DAPLINK USB drive should include a DETAILS.TXT file.
If an ERROR.TXT file exists on the drive, check that the FTHR board had power during the programming process
and repeat steps 3 and 4.
5) To ready the FTHR board for use, disconnect the DAPLINK board (ribbon cable) and press the Reset button on the
FTHR board or disconnect the FTHR board from the USB power supply.
a. When the Reset button is pressed, the microcontroller will restart and the newly programmed application will
begin to run, or you can disconnect and reconnect the USB cable if using a PC for power.
The latest information and these firmware update instructions can be found on the MAX32630FTHR board mBed web
site or by visiting the mBed home page and searching for “MAX32630FTHR”.
If you do not have an mbed account, choose Signup and create your mbed account. Otherwise, log in with your normal
username and password. This will give you access to the website, tools, libraries, and documentation.
You must load the matching HDK image (MAX32630FTHR DAPLINL image) for the platform you are programming in
order for drag-n-drop programming to work.

Appendix II – Hardware Modifications

I C Pull-Up Resistors
To accommodate the various operating modes of the MAX4147X products on one board, the shared digital pins have
many interface modes over which they operate.
To properly establish the open-drain topology of the two-pin serial interface the user must have the SDA and SCL lines
pulled-up to the supply voltage. The resistor footprints: R8 and R9 are provided on the MAX4147XEVKIT for this purpose.
By connecting JU3 (1-2 and 3-4) both lines will be pulled-up to the VDD supply.
2
Figure A2-1. I C Pull-Up Resistors
These pull-ups should only be connected when the I2C/PRESET pin is connected to VDD (JU2 1-2), thus selecting the
2
I C interface mode of the MAX4147X.
2
It should be noted that the FTHR board also has footprints for I C pull-up resistors at R6 and R11. Both sets of pull-up
resistors (on the FTHR board and the MAX4147XEVKIT) should not be populated simultaneously, otherwise incorrect
2
2
I C signal levels may result. Likewise, if other I C slaves are added to the bus, only one set of pull-up resistors should
be used.
PMOD Header Interface
The MAX4147X EV kit provides a PMOD-compatible header footprint, which provides yet another built-in interface to the
transmitter. The JU4 connector can be populated with a 6-pin, 100mil, right-angle header such as a SAMTEC TSW-106-
25-T-S-RA, allowing direct connections to the CSB/I2C, SDIO/RSSI, SCL, SCLK/SDA, ground, and VDD lines.
The PMOD interface can be used in combination with the Maxim MAX32600MBED kit and the MAXREFDES72# Arduino
Uno R3-to-PMOD shield adaptor. When using the PMOD interface to supply the MAX4147X EV kit with power, be sure
to connect the JU1 jumper between pins 2-3.
