User’s Manual 11. I NTRODUCTIONThe RCM4200 series of RabbitCore modules is one of the nextgeneration of core modules that take advantage of new Rabbit ®4000 features such as hardware DMA, clock speeds of up to60 MHz, I/O lines shared with up to six serial ports and fourlevels of alternate pin functions that include variable-phasePWM, auxiliary I/O, quadrature decoder, and input capture.Coupled with more than 500 new opcode instructions that help toreduce code size and improve processing speed, this equates to acore module that is fast, efficient, and the ideal solution for a widerange of embedded applications. The RCM4200 also features anintegrated 10/100Base-T Ethernet port, an A/D converter, and aserial flash memory for mass storage.Each production model has a Development Kit with the essentialsthat you need to design your own microprocessor-based system,and includes a complete Dynamic C software development sys-tem. The Development Kits also contains a Prototyping Boardthat will allow you to evaluate the specific RCM4200 module andto prototype circuits that interface to the module. You will alsobe able to write and test software for the RCM4200 modules.Throughout this manual, the term RCM4200 refers to the complete series of RCM4200RabbitCore modules unless other production models are referred to specifically.The RCM4200 has a Rabbit 4000 microprocessor operating at up to 58.98 MHz, staticRAM, flash memory, serial flash mass-storage option, an 8-channel A/D converter, twoclocks (main oscillator and timekeeping), and the circuitry necessary for reset and man-agement of battery backup of the Rabbit 4000’s internal real-time clock and 512K of staticRAM. One 50-pin header brings out the Rabbit 4000 I/O bus lines, parallel ports, A/Dconverter channels, and serial ports.The RCM4200 receives its +3.3 V power from the customer-supplied motherboard onwhich it is mounted. The RCM4200 can interface with all kinds of CMOS-compatibledigital devices through the motherboard.
