Analog core module has 10/100Base-T reference design speeds OEM time-to-market

12 February 2003 DSP, Micros & Memory

Rabbit Semiconductor's newest RCM3400 core module is the company's first RabbitCore with analog, and provides a 10/100Base-T reference design. The RCM3400 is an ideal option for designers who want to supercharge embedded systems development and speed time-to-market. Measuring only 35 x 29 x 7,4 mm, RabbitCores mount directly on a user-designed motherboard and can interface with all manner of CMOS-compatible digital devices. They also contain built-in low-EMI features, including a clock spectrum spreader, that practically eliminate EMI problems, helping OEMs pass CE and regulatory RF emissions tests.

Powered by the Rabbit 3000 microprocessor, an efficient 8-bit core module, it operates at 3,3 V (with 5 V-tolerant I/O), while running at 29,4 MHz. Two models offer 512 K Flash/512 K SRAM or 265 K Flash/256 K SRAM and both are equipped with quadrature decoder, PWM outputs, and pulse capture capabilities. Two 34-pin connection headers provide 47 digital I/O (41 alternate) shared with the five serial ports. All RCM3400 models ship with pre-assigned MAC IDs allowing easy networking using the 10/100Base-T reference design on the development board.

The RCM3400 features a battery-backable realtime clock, glueless memory and I/O interfacing, and low-power 'sleepy' modes. A fully enabled slave port permits easy master-slave interfacing between processor-based systems, and an alternate I/O bus can be configured for eight data lines and six address lines (shared with parallel I/O). The Rabbit 3000 processor's compact, C-friendly instruction set and high clock speeds produce fast results for math, logic, and I/O.

Programs are developed with Rabbit's Dynamic C development system. This is a C-language environment that includes an editor, compiler, and in-circuit debugger (Dynamic C SE is included in low-cost development kits). 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 code.
