Microprocessor core module with integrated Ethernet connectivity

24 September 2003 Computer/Embedded Technology

The RCM3200 RabbitCore microprocessor core module is an ideal option for designers who want to rapidly develop and implement embedded systems with fully integrated 10/100Base-T Ethernet connectivity, says manufacturer, Rabbit Semiconductor.

Measuring only 69 x 47 mm, the RCM3200 operates at 3,3 V (5 V-tolerant I/O), runs at up to 44,2 MHz, and features six 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 six serial ports and alternate I/O features. The integrated 10/100Base-T Ethernet port allows realtime local or worldwide connectivity.

The RCM3200 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 with another processor-based system, 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 exceptionally fast results for math, logic, and I/O.
