RCM4100 RabbitCore®
Models RCM4100, RCM4110, RCM4120
Description
The RCM4100 microprocessor core modules are compact, powerful control devices for embedded applications that require I/O control, data handling, and peripheral connectivity.
The RCM4100 series is the first of the next generation core modules to take advantage of the Rabbit® 4000 microprocessor. The Rabbit 4000 features a clock speed of up to 60 MHz, hardware DMA, auxiliary I/O, quadrature decoder, input capture, 40 GPIO lines shared with up to six serial ports, and four levels of alternate pin functions that include variable phase PWM. The 500+ new operational code instructions increase processing efficiency. The RCM4100 series features a small footprint of 1.41” x 1.88” (36 mm x 48 mm), complete with the Rabbit 4000 microprocessor, 512K Flash, and 256K or 512K data SRAM. The RCM4100 model adds an 8-channel A/D converter. Three versions are available for varying speeds and memory options. The RCM4100 core modules provide the I/O control and connectivity for a wide range of real-world embedded applications.
RabbitCores mount directly onto a user-designed motherboard, and can interface with CMOS-compatible digital devices via the user’s motherboard. Programs are developed with our industry-proven Dynamic C® development system, a C language environment that includes an editor, compiler, and in-circuit debugger. Programming is easy with hundreds of samples and libraries that are pre-developed, for a user to be up and running in no time. No in-circuit emulator is required, no third party tools needed.
Dynamic C ensures optimal support for Rabbit 4000-based solutions. Dynamic C enhanced compiler generates smaller code, support for far pointers and far data for easy access to external memory devices, improvements to AES encryption libraries, and a new I/O configuration utility that helps assign pin functions and guides those selections so that conflicts can be avoided.
