The RCM3750 features 10/100Base-T connectivity, 512K Flash / 512K SRAM, 4 serial ports, and an extremely small footprint (2.95" × SRC="../images/DevKits_teez.gif" width="423" height="92" border="0">

This RabbitCore mounts directly on a user-designed motherboard with a single 0.1”

The Rabbit 3000 microprocessor, RCM3750, and Dynamic C were designed in a complementary fashion for maximum performance and ease of use in embedded systems. Rabbit Semiconductor’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.

Programming the RCM3750
Programs are developed using Rabbit Semiconductor's industry-proven Dynamic C software development system. An extensive library of drivers and sample programs is provided.
