13 Device and Documentation Support

13.1 Device Support

13.1.1 Development Support

The application firmware for the UCD3138xA is developed on Texas Instruments Code Composer Studio (CCS)

integrated development environment.

Device programming, real time debug and monitoring/configuration of key device parameters for certain power

topologies are all available through Texas Instruments’ FUSION_DIGITAL_POWER_DESIGNER Graphical User

Interface (http://www.ti.com/tool/fusion_digital_power_designer). The FUSION_DIGITAL_POWER_DESIGNER

software application uses the PMBus protocol to communicate with the device over a serial bus using an

interface

adaptor

known

the

USB-TO-GPIO,

available

EVM

from

Texas

Instruments

(http://www.ti.com/tool/usb-to-gpio). PMBUS-based real-time debug capability is available through the ‘Memory

Debugger’ tool within the Device GUI module of the FUSION_DIGITAL_POWER_DESIGNER GUI, which

represents a powerful alternative over traditional JTAG-based approaches’.

The software application can also be used to program the devices, with a version of the tool known as

FUSION_MFR_GUI optimized for manufacturing environments (http://www.ti.com/tool/fusion_mfr_gui). The

FUSION_MFR_GUI tool supports multiple devices on a board, and includes built-in logging and reporting

capabilities.
