Silicon Explorer II is a CMOS device and exhibits very low current
consumption when idle. Current consumption rises rapidly to several
hundred milliamps during acquisition. If your power supply is unable
to supply the necessary current, SE II or your target may reset.
Table 1-2 is a guide to typical current consumption based on an
acquisition rate at 5V — current will be proportionately higher at 3V.

Acquisition Rate
Silicon Explorer II has a 22-pin (18 channels, a clock, VIO, GND, and
clock GND) and a 16-pin connector for controlling the ActionProbe
circuitry and reading the design checksum. Silicon Explorer II Lite has
only the 16-pin and 26-pin connector (the large 26-pin connector is not
used). Table 1-3 is a summary of the connector pins and their
functions.
