10/100Base-T Core Module for Rapid Embedded Systems Development

Davis, Calif., September 17, 2002 - Rabbit Semiconductor's fastest and most powerful microprocessor core module to date, the RCM3200 RabbitCore is the ideal option for designers who want to rapidly develop and implement embedded systems with fully integrated l0/100Base-T Ethernet connectivity. Measuring only 2.73" x 1.85" (69 x 47 mm), the RCM3200 operates at 3.3 V (with 5 V-tolerant I/O), runs at 44.2 MHz, and features 6 serial ports. Built-in low-EMI features, including a clock spectrum spreader, practically eliminate EMI problems, helping OEMs pass CE and regulatory RF emissions tests.

Powered by the Rabbit 3000 microprocessor, the RCM3200 is equipped with 512K Flash, 512K program execution SRAM and 256K data SRAM, quadrature decoder, PWM outputs, and pulse capture capabilities. Two 34-pin connection headers provide 52 digital I/O shared with the 6 serial ports and alternate I/O features. The integrated 10/100Base-T Ethernet port allows real-time local or (69x47 22mm) worldwide connectivity.

The RCM3200 features a battery-backable real-time clock, glueless memory and I/O interfacing, and low-power "sleepy" modes. A fully enabled slave port permits easy master-slave interfacing with another processor-based system, and an alternate I/O bus can be configured for 8 data lines and 6 address lines (shared with parallel I/O). The Rabbit 3000 processor's compact, C-friendly instruction set and high clock speeds produce exceptionally fast results for math, logic, and I/O.

RabbitCores mount directly on a user-designed motherboard and act as the controlling microprocessor for the user's system. RabbitCores can interface with all manner of CMOS-compatible digital devices through the user's motherboard.

Programs are developed with our industry-proven Dynamic C® 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.

Priced from $63 (qty. 1000), RCM3200 models are available to ship September 30. A complete RCM3200 Development Kit is priced at $349 and includes RabbitCore module (RCM3200 with 512K Flash, 512K program execution SRAM, and 256K data SRAM), prototyping board, AC adapter (U.S. only), serial cable for programming
and debugging, Getting Started manual, and complete Dynamic C SE software development system (not a trial version) with royalty-free TCP/IP and documentation on CD-ROM.
