3.1 Default Addresses
The default 9-bit I2C address of DS90UB95xis set to 0x30 (011 0000) using suitable resistor divider on ID[x] pin.
Also, 8-bit I2C address of DS90UB954 (or variant) is set to 0x7A (0111 1010) using suitable resistor dividers on
pins IDX[0] and IDX[1].

There are two methods to use the USB2ANY to communicate with the 953/954 EVMs. The first method is to
simply connect the USB to Mini-USB cable to the USB port of your computer and the Mini-USB ports on the
EVMs, J9 for the 953 EVM (see
) and J2 on the 954 EVM. If using the first method, skip to
The second method is to use the pinout of the USB2ANY.
