The RCM3200 has a Rabbit 3000^® microprocessor operating at 44.2 MHz, data and program execution SRAM, flash memory, two clocks (main oscillator and timekeeping), and the circuitry necessary for reset and management of battery backup of the Rabbit 3000's RCM3200 internal real-time clock and the data SRAM. Two 34-pin headers bring out the Rabbit 3000 I/O bus lines, parallel ports, and serial ports.

The RCM3200 receives its +3.3 V power from the customer-supplied motherboard on which it is mounted. The RabbitCore RCM3200 can interface with all kinds of CMOScompatible digital devices through the motherboard.
