D.1 Power Supplies
The RCM3200 requires a regulated 3.3 V ± 0.15 V DC power source. The RabbitCore
design presumes that the voltage regulator is on the user board, and that the power is made
available to the RCM3200 board through header J2.
An RCM3200 with no loading at the outputs operating at 29.4 MHz typically draws 145 mA.
The RCM3200 will consume an additional 10 mA when the programming cable is used to
connect the programming header, J3, to a PC.
D.1.1 Battery Backup
The RCM3200 does not have a battery, but there is provision for a customer-supplied bat-
tery to back up the data SRAM and keep the internal Rabbit 3000 real-time clock running.
Header J2, shown in Figure D-1, allows access to the external battery. This header makes
it possible to connect an external 3 V power supply. This allows the SRAM and the inter-
nal Rabbit 3000 real-time clock to retain data with the RCM3200 powered down.
A lithium battery with a nominal voltage of 3 V and a minimum capacity of 165 mA·h is
recommended. A lithium battery is strongly recommended because of its nearly constant
nominal voltage over most of its life.
User’s Manual
Appendix D provides information on the current requirements
of the RCM3200, and includes some background on the chip
select circuit used in power management.
