Device and Documentation Support

8.1

Device Support

The application firmware for the UCD3138064A is developed on Texas Instruments Code Composer

Studio (CCS) integrated development environment (v3.3 recommended).

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 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_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.
