13 Device and Documentation Support

13.1 Device Support

The application firmware for the UCD3138064 is developed on Texas Instruments Code Composer Studio (CCS)

integrated development environment. Version 6.2 is recommended for new designs. Designs done with Version

3.3 are still perfectly acceptable as well.

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 Studio Graphical User

Interface (http://www.ti.com/tool/FUSION-DIGITAL-POWER-STUDIO). The Fusion Digital Power Studio software

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

known as the USB-TO-GPIO, available as an 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 Studio 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

Production Tool optimized for manufacturing and production environments (https://www.ti.com/tool/FUSION-

PRODUCTION-GUI). The Fusion Production Tool supports multiple devices on a board, and includes built-in

logging and reporting capabilities.
