APPENDIX C. POWER SUPPLY
Appendix C provides information on the current requirements of
the RCM4200, and includes some background on the chip select
circuit used in power management.
C.1 Power Supplies
The RCM4200 requires a regulated 3.0 V – 3.6 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 RCM4200 board through header J2.
An RCM4200 with no loading at the outputs operating at 58.98 MHz typically draws
240 mA, and may draw up to 275 mA at 3.6 V and 85°C; the corresponding current draw
for the RCM4210 is typically 200 mA, and up to 225 mA at 3.6 V and 85°C.
C.1.1 Battery Backup
The RCM4200 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 4000 real-time clock running.
Header J2, shown in Figure C-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 4000 real-time clock to retain data with the RCM4200 powered down.
Figure C-1. External Battery Connections
at Header J2
A lithium battery with a nominal voltage of 3 V and a minimum capacity of 165 mAh is
recommended. A lithium battery is strongly recommended because of its nearly constant
nominal voltage over most of its life.
