10/100Base-T core module accelerates embedded development

Rabbit Semiconductor has announced the availability of the RCM3200 RabbitCore microprocessor core module that enables designers to rapidly develop and implement embedded systems with fully-integrated 10/100Base-T Ethernet connectivity.

The 69-by-47mm board operates from a 3.3V source with 5V-tolerant I/O, runs 44.2MHz, and features six serial ports. It also includes a clock spectrum spreader to help lower EMI and allow compliance to CE and regulatory RF emissions tests.

The module is powered by the Rabbit 3000 microprocessor and is equipped with 512K of 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 RCM3200 features a battery-backable real-time clock, glueless memory and I/O interfacing, and low-power "sleepy" modes. A slave port permits 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).

As with other RabbitCore products, the RCM3200 can be mounted directly on a user-designed motherboard and act as the controlling microprocessor for the user's system.
