Rabbit Semiconductor Introduces the new RCM3750 10/100Base-T Ethernet Rabbitcore Module

August 25, 2005; Davis, CA - Rabbit Semiconductor is pleased to announce the release of the new RCM3750 RabbitCore(TM) module. Features include a powerful Rabbit 3000® microprocessor running at 22.1 MHz, 10/100Base-T connectivity, 512K of Flash and 512K SRAM, 1 MB of serial Flash, 4 serial ports, 33 digital I/O, small foot print, and low power. The RCM3750 starts at $61, qty. 100. The development kit price starts at $329. Extensive demo programs and software application templates make it easy to get the RCM3750 up and running in no time. Available software modules enable rapid development of secure web browser interfaces for embedded system control. The RCM3750 is the perfect solution for Ethernet / Internet based embedded control systems. 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 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.
