ST2100

Electrical characteristics

This section provides electrical specifications for the STreamPlug ST2100 device.

7.1

Absolute maximum ratings

This product contains devices to protect the inputs against damage due to high/low static

voltages. However it is advisable to take normal precaution to avoid application of any

voltage higher/lower than the specified maximum/minimum rated voltages.

The absolute maximum ratings shown in Table 19 are the maximum stress that can be

applied to a device without causing permanent damage. However, extended exposure to

minimum/maximum ratings may affect long term device reliability.

7.2

Power consumption

In Table 20 and Table 21 power consumption data are based on bench measurements with

devices using the Linux OS, the CPU and DDR2 running at 333 MHz and all on-chip

peripherals and internal modules enabled while the STreamPlug ST2100 is transferring

a file from the USB Flash memory to the powerline.
