 Rabbit Semiconductor has released the RCM3750 RabbitCore
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.
RabbitCore mounts 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 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 for performance and use in embedded systems. Rabbit Semiconductor’s
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. The RCM3750 is a
solution for Ethernet / Internet based embedded control systems.
The RCM3750 starts at $61, qty. 100. The development kit price starts at
$329.
