Powered by the Rabbit 3000 microprocessor running at 44,2 MHz, the RCM3200 is equipped with 512 K Flash, 512 K program execution SRAM and 256 K data SRAM, quadrature decoder, PWM outputs, and pulse capture capabilities. Two 34-pin connection headers provide 52 digital I/O shared with the six serial ports and alternate I/O features. The integrated 10/100Base-T Ethernet port allows realtime local or worldwide connectivity.

A unique feature of the RCM3200 is that it uses a 'fast RAM' in the form of a 512 K device with a 15 ns access time. The Dynamic C downloads code into the 512 K flash and once download is complete and it senses that the module is an RCM3200, it will copy the code into this fast RAM and the module will run from there. The 256 K of data SRAM is the standard battery-backable memory for data storage.

The RCM3200 is similar to the RCM3000 module from Rabbit but the RCM3200 is capable of faster Ethernet communications with a 10/100 BaseT Ethernet chipset. The RCM3200 has the same footprint as the RCM3000/RCM3100 (69 x 47 x 22 mm) as well as same pin signals so it can be a drop-in replacement for customers that need a higher throughput Ethernet as well as more memory.

RabbitCores mount directly on a user-designed motherboard and act as the controlling microprocessor for the user's system. RabbitCores can interface with all types of CMOS-compatible digital devices through the user's motherboard. Programs are developed with Rabbit's Dynamic C SE development system, a C-language environment that includes an editor, compiler, and in-circuit debugger (Dynamic C SE is included free of charge in low-cost development kits). Efficient hardware and software integration facilitates rapid design and development. User programs can be compiled, executed, and debugged using Dynamic C and a programming cable-no in-circuit emulator is required. An extensive library of drivers and sample programs is provided, along with royalty-free TCP/IP stack with source.
