3.10 Power Connectors
The CYCLONE programmers provide a Target Power Supply Input Jack and a Target Power
Supply Output Jack with 2.5/5.5 mm Pin Diameter. The power jacks are connected or
disconnected by two electromechanical relays. When connected, the Center Pin of the Target
Power Supply Input Jack is connected to the Center Pin of the Target Power Supply Output Jack.
When disconnected, both terminals of the Target Power Supply Output Jack are connected to
GND via a 1W, 100 Ohm resistor. The location of Target Power In is shown in
Figure 3-3 , and the
location of Target Power Out is shown in Figure 3-3 .
3.11 Reset Button
The Reset Button performs a hard reset of the Cyclone system. The location of the Reset Button is
shown in
Figure 3-3 .

3.12 Optional Oscillator (MON08 Only)
CYCLONE programmers with MON08 support (PEmicro Part# CYCLONE_UNIVERSAL only)
provide a software configurable 9.8304MHz or 4.9152 MHz oscillator clock signal to Pin 13 of the
MON08 Connector. The user may use this clock signal to overdrive the target RC or crystal
circuitry. If this signal is not used, just leave Pin 13 of the target MON08 header unconnected.
Please note that if the target already uses an oscillator as its clock, the Cyclone will NOT be able to
overdrive it. The clock should have sufficient drive to be used with a target system even if the
target system has an RC circuit or crystal connected.
Note:
3.13 Cyclone Time / Real Time Clock
CYCLONE programmers are equipped with a Real Time Clock (RTC) module designed to keep
