The UCD3138A64CEVM-660 is similar to the UCD3138CC64EVM-030. The UCD3138A64CEVM-660 is
used either as a stand-alone control card to study the UCD3138A64 controller IC or as a DPWM controller
board working with a power stage board to implement a fully-regulated power converter. To help the
targeted off-line isolated power applications, this EVM has been designed to work seamlessly with two
power converter EVMs offered by TI: UCD3138PSFBEVM-027, and UCD3138LLCEVM-028. Contact
Texas Instruments for assistance obtaining the firmware source code used to interface the UCD3138A64
with these EVMs, which were originally developed to support the UCD3138 device. Alternately, the EVM
can also be loaded with custom-developed firmware. In order to communicate with the UCD3138A64
digital controller in this EVM, a separate USB interface adapter EVM from Texas Instruments known as
the USB-TO-GPIO Adapter is required. The USB-TO-GPIO Adapter is NOT supplied with
UCD3138A64CEVM-660 evaluation module and must be purchased separately. Texas Instruments also
offers a Graphical User Interface (GUI) in order to program the UCD3138A64 controller and configure
parameters when used with the two power converter EVMs.

Description
UCD3138A64CEVM-660 is an EVM board, functioning as a control card for UCD3138A64PFC digital
power supply applications. This EVM is used to control a power converter topology such as LLC Resonant
Half-Bridge DC converter, and Phase-Shifted Full-Bridge DC converter, and so forth, by downloading the
associated firmware and interfacing with an appropriate power stage board. When coupled with the
appropriate corresponding firmware, the EVM works seamlessly with the following EVM boards:
• UCD3138PSFBEVM-027, A Digital Controlled Phase-Shifted Full-Bridge DC-to-DC Converter
Evaluation Board
• UCD3138LLCEVM-028, A Digital Controlled LLC Half-Bridge DC-to-DC Converter Evaluation board
Contact Texas Instruments for assistance with obtaining the firmware source code used to interface the
UCD3138A64 with these EVMs.

Configuring the EVM to Access EEPROM SPI or I2C Communication with
UCD3138A64
The UCD3138A64CEVM-660 contains all the features of the UCD3138CC64EVM-030. However, the
UCD3138A64CEVM-660 adds two programmable EEPROM devices for use with the UCD3138A64
device – one accessed via SPI communication port and the other via the 2nd I2C port in UCD3138A64.
Additionally, unlike the UCD3138064EVM-166, both EEPROMs can be accessed by the device
simultaneously, since both SPI and I2C hardware have been assigned dedicated pins. Appropriate
firmware is necessary to configure the UCD3138A64 device to choose the communication port desired.
No hardware changes are required to interface with either the SPI or I2C EEPROMs.
• To choose I2C EEPROM, connect jumpers J9 and J10, each in position 1 (Pins 1 and 2). Also, make
sure J7 and J8 are disconnected.
• To choose SPI EEPROM, connect jumpers J7 and J8 as well as jumpers J9 and J10, each in position
2 (Pins 2 and 3).

Appendix A Summary of Using Code
Composer Studio v5.5
In this appendix, the basic steps of using Code Composer Studio v5.5 to compile firmware for the
UCD3138 family of devices is described. A design flow is described but detailed steps for firmware code
creation, and firmware and hardware debugging are beyond the scope of this user’s guide.
A.1
Importing a CCSv5 Project
Upon running CCSv5.5 for the first time, the Workspace Launcher window appears as shown in
Figure 13. The user decides whether or not to use a workspace, where it is located, or to check the box
that says Use this as the default and do not ask again. For this guide, a workspace is not used, so click
OK.

Importing a CCSv5 Project
www.ti.com
When the main window opens, click Project in the top navigation menu, then choose Import Existing
CCS Eclipse Project as shown in Figure 14.
Figure 14. Import Existing CCS Eclipse Project
This opens the window shown in Figure 15. Under Select search-directory, click Browse, navigate to the
target project, and click OK. For this example, the project is called Training_CCSv5.5 and is located in a
folder called Training_CCS5v5. Check the box next to the discovered project, and do not check Copy
projects into workspace, or Automatically import referenced projects. Click Finish.

Build/Compile a Project Using Code Composer Studio v5.5
A.2
www.ti.com
Build/Compile a Project Using Code Composer Studio v5.5
For the UCD3138 family of devices, compiling a project produces an Intel-hex (.x0) firmware file that can
be downloaded to, and run on the UCD3138 or related target device using the UCD3XXX / UCD9XXX
Device GUI (part of the Fusion Design Online software from TI).
After editing the project files, Right-Click on the project in the Project explorer, and choose Build Project.
NOTE: If this is the first time building a UCD3138 or related project, and Cygwin is also installed on
the PC that is performing the compilation, the instructions in Section 3.3 of the Application
Note Converting UCD3138 Firmware Project from Code Composer Studio Version 3.3 to 5.2
(SLUA679) must be followed. Mainly, the C:\CYGWIN or other similarly named directory
must be renamed temporarily during this first build. This allows the new ARM library to be
built properly. After this first build, the CYGWIN directory can be rolled back to its original
name, and future builds can compile successfully.
Builds may take up to a minute or longer to compile for a first time build. Figure 17 shows the state of a
successful build:
Figure 17. Successful Build of UCD3138-Related Source Code
When the build has finished, the .x0 file is created and is placed in the project directory’s debug folder.
The filename that prefaces the .x0 is the name of the project that was built (that is, a project named
Training_CCS5v5 creates Training_CCS5v5.x0 as its firmware file). However, it must be noted that the
project name must have no spaces, otherwise the .x0 file is not generated.
This .x0 file can be run on the UCD3138 target device using the UCD3XXX / UCD9XXX Device GUI.

to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
