Silicon Explorer II Quick Start

Actel designed Silicon Explorer II hardware to withstand abuse
normally found in a lab environment. However, long term exposure to
out-of-range conditions can cause failure. In particular, long term
connection to reverse- or over-voltage power conditions can cause
thermal failure.
Current Consumption
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 2
is a guide to typical current consumption based on an acquisition rate
at 5V — current will be proportionately higher at 3V.

Silicon Explorer II has a 22-pin (18 channels, a clock, VCC, GND, and
clock GND) and a 16-pin connector for controlling the ActionProbe
circuitry and reading the design checksum. Actel uses the 26-pin
connector for programming ProASIC devices. Silicon Explorer Lite has
