4. TRF79x0ATB Module(s) Description
The TRF79x0ATB Evaluation Modules are intended to allow the software application
developer to get familiar with the functionalities of either of the TRF79x0A MultiStandard Fully Integrated 13.56 MHz NFC/RFID reader ICs with the freedom to
develop on their Texas Instruments Embedded microcontroller development platform
of choice.
The TRF79x0ATB module is also intended to allow customer driven antenna tuning
with onboard coil and customer driven antenna form factor design.
The module is hard wired for SPI communications, supports Slave Select and
TRF79x0A Direct Mode 2 (default), Direct Mode 1 and Direct Mode 0 operations.
The user also has access to and full control over the TRF79x0A EN2 and EN lines,
allowing for design and development of ultra low power NFC/HF RFID systems.
The module has an onboard boost converter (TPS61222DCKT) which boosts
+3.3VDC in to +5VDC out to TRF79x0A IC for +23dBm (full transmitter power out)
operations.
An impedance matching circuit from 4Ω to 50Ω is populated on the module and this
is connected to a tuned 50Ω antenna circuit which consists of onboard four turn coil
with series and parallel passive elements (capacitors and a resistor).
Test points are available on the board for checking firmware operations with
oscilloscope or logic analyzer, impedance matching and for attaching external antenna.
Connection to Texas Instruments Microcontroller platforms are made via Samtec EM
headers located on the underside of the board (Connectors P1/RF1 and P2/RF2).

7. MSP-EXP430F5438 Experimenters Board
The MSP430F5438 Experimenter Board (MSP-EXP430F5438) is a development
platform for the latest generation MSP430 MCUs. It features a 100-pin socket which
supports the MSP430F5438 (datasheet) and other devices with similar pinouts. The
socket allows for quick upgrades to newer devices or quick applications changes. It is
also compatible with many TI low-power RF wireless evaluation modules such as the
CC2520EMK and the TRF79x0ATB module discussed here in this document.
The Experimenter Board helps designers quickly learn and develop using the new
F5xx MCUs, which provide the industry’s lowest active power consumption, more
memory and leading integration for applications such as energy harvesting, wireless
sensing and automatic metering infrastructure (AMI).
A TI Flash Emulation Tool, like the MSP-FET430UIF, is required to program and
debug the MSP430 devices on the experimenter board.
The TRF79x0ATB module plugs into the RF1 and RF2 headers on this MSP-EXP
board (see Figure 3). For logic analyzer connection during firmware debug, user can
use test points on TRF79x0ATB board or pins on header RF3.

13. Antenna Tuning Details
Module antenna as shipped is tuned for 50Ω impedance at 13.56MHz. It has a
nominal bandwidth of 1.3MHz, which results in a quality factor of
approximately 10. Module antenna circuit has a board mounted U.FL
connector installed for users that want to experiment with different tuning
solutions or disconnect onboard antenna and experiment with antennas of their
own design or application. Below are some design/application notes for users
to reference if they want to change the antenna Q factor or experiment further
on their own in order to serve their particular application directly.
TRF79x0ATB coil antenna tuning details starts with calculations to produce
the theoretical values shown below (and based on measurements of antenna
coil on Rev B board.) Coil value nominally measures 0.95uH at 13.56MHz
and

Certain Instructions. It is important to operate this EVM within TI’s
recommended specifications and environmental considerations per the user
guidelines. Exceeding the specified EVM ratings (including but not limited to
input and output voltage, current, power, and environmental ranges) may
cause property damage, personal injury or death. If there are questions
concerning these ratings please contact a TI field representative prior to
connecting interface electronics including input power and intended loads.
Any loads applied outside of the specified output range may result in
unintended and/or inaccurate operation and/or possible permanent damage to
the EVM and/or interface electronics. Please consult the EVM User's Guide
prior to connecting any load to the EVM output. If there is uncertainty as to
the load specification, please contact a TI field representative. During normal
operation, some circuit components may have case temperatures greater than
60 C as long as the input and output are maintained at a normal ambient
operating temperature. These components include but are not limited to linear
regulators, switching transistors, pass transistors, and current sense resistors
which can be identified using the EVM schematic located in the EVM User's
Guide. When placing measurement probes near these devices during normal
operation, please be aware that these devices may be very warm to the touch.
As with all electronic evaluation tools, only qualified personnel
knowledgeable in electronic measurement and diagnostics normally found in
