1 Description
UCD90SEQ64EVM-650 allows any of TI’s 64-pin sequencers to be installed into the onboard socket for
evaluation. Access to all of the user input/output (I/O) is provided via strip connectors for integration into
complex systems using clip-type jumper wires.
UCD90SEQ64EVM-650 allows direct PMBus (power management bus) communication with the
sequencer via an onboard USB interface. This interface allows direct control of and feedback from the
sequencer when using the TI Fusion Digital Power Designer graphical user interface (GUI).

2 Quick Start
2.1 Test Setup
Figure 1 shows a typical test setup for UCD90SEQ64EVM-650. All that is required is a personal computer
(PC) with a USB port and the TI Fusion Digital Power Designer GUI. The USB-EVM cable is provided with
the EVM and is used for EVM power.
When installing other UCD90xxx sequence devices into XU1, ensure that the device pin 1 is oriented as
shown in Figure 1.
