This appendix provides information for the power supplies on the PowerCore modules used on the Rabbit-
FLEX BL300F board. Information on the reset generator used in power management is also included.
B.1 Power Supplies
The PowerCore module has a 6-pin locking connector on the top side at J3 designed to accept a wire har-
ness that brings in power. The J3 label on the PowerCore module is difficult to see, but luckily the 6-pin
locking connector is easy to find.
The PowerCore module receives power in the form of unregulated AC. There is an onboard +5 V DC
switching regulator that is available in 1 A (PowerCore 3810) and 2 A (PowerCore 3800). The +5 V DC is
regulated down to 3.45 V by a linear regulator on the PowerCore module.

The PowerCore 3800 and the PowerCore 3810 are built for use with a full-wave rectifier and center-tapped
AC transformer.
