Continuing its focus on bringing more connectivity options to developers of Z80-type based MCU designs, Rabbit has just released its RCM3750 RabbitCore module.
Designed for Ethernet/Internet-based embedded control systems, the module, it features a 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 module mounts directly on a user-designed motherboard with a single 0.1 inch (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.
The RCM3750 starts at $61 in 100 unit quantities. 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 development includes the Dynamic C development system with a C language environment that incorporates 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.
