RCM3700 RabbitCore®
Models RCM3700, RCM3710, RCM3720
Description
The RCM3700 RabbitCore is the lowest priced Rabbit® 3000 microprocessor based core module designed for Ethernet/Internet applications. The RCM3700 features 512K Flash / 512K SRAM or 256K Flash / 128K SRAM, 4 serial ports, and an extremely small footprint (2.95" × 1.20" / 75 × 30 mm). The RCM3710 is the least expensive of the Ethernet/Internet enabled Rabbit 3000 microprocessor based RabbitCores starting at $39, qty. 100. The development kit price is $299. Extensive demo programs and software application templates make it easy to get the RCM3700 up and running in record time.
This RabbitCore mounts directly on a user-designed motherboard with a single 0.1" (2.54 mm) 2x20 dual-row IDC header and can interface with all manner of CMOS-compatible digital devices. 33 digital I/O (shared with serial ports), power, and other signals are routed directly to the motherboard. Built-in low EMI features, including a clock spectrum spreader, practically eliminate EMI problems, helping OEMs pass European CE and other regulatory RF emissions tests.
The RCM3700 is equipped with +5 VDC tolerant I/O, quadrature encoder inputs, PWM outputs, and pulse capture and measurement capabilities. The RCM3700 also features a battery-backable real-time clock, glueless memory and I/O interfacing, and low-power "sleepy" modes. An alternate I/O bus can be configured for 8 data lines and 6 address lines (shared with parallel I/O).
Programmed with Rabbit's Dynamic C® integrated development environment, the RCM3700 executes math, logic, and I/O exceptionally quickly. The Rabbit 3000 microprocessor, RCM3700, and Dynamic C were designed in a complementary fashion for maximum performance and ease of use in embedded systems. Rabbit's industry-proven Dynamic C development system is a C language environment that includes an editor, compiler, and in-circuit debugger. 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, including royalty-free TCP/IP stack with source code.

Designing with RabbitCores
The RabbitCore family of microprocessor core modules is designed to facilitate rapid development and implementation of embedded systems. RabbitCores are powered by high-performance 8-bit Rabbit microprocessors with extensive integrated features and a C-friendly instruction set designed for use with the Dynamic C® development system. The RabbitCore mounts on a user-designed motherboard and acts as the controlling microprocessor for the user's system. Small in size but packed with powerful features, these core modules give designers a complete package for control and communication.
