2.2 Power Requirements

TXE81XXEVM has a few different options for powering the board. When the TXE81XX is powered, the "BOARD POWER" indicator D9 lights up. This means that power is being applied to the board. This does not necessarily mean that the DUT is powered at this time. To confirm power at the DUT, J14 must be shorted. The board supports 5V and 3.3V USB power through the USB2ANY Explorer GUI. The Total Phase or "TP" jumper J25 connects the power from Total Phase products listed: SPI Aardvark, Cheetah SPI, Promira Serial Platform. TXE81XXEVM permits external power connection through a separate power source.

When jumping power connections, see guidelines in Table 2-1. Only 1 power option can be shorted to VCC at a single time. This includes 3.3V USB2ANY, 5V USB2ANY, TP power, or and external power supply connection at the test point TP1.

Note: Only 1 jumper option cab be enabled at a single time. 5V, 3.3V, or TP can be selected individually, never together. This also includes power coming from an external source on the VCC test point (TP1). Once the power connection is selected, short the power header J14 to enable power to the DUT.

J7 USB2ANY 5V to VCC connection
J10 USB2ANY 3.3V to VCC Connection
J25 Total Phase Power Connection (+ 3.3V)
J14 Connects power from USB2ANY, Total Phase product, or external power connection to the DUT. This header can be used to measure current flow to the TXE81xx.
