RCM3400 RabbitCore
TM
Analog Core ModuleWith 10/100Base-T Reference Design
Models RCM3400, RCM3410
The RCM3400 analog RabbitCore provides a known-good processor and analog input subsystem for OEMs to quickly integrate into
custom designs. The RCM3400 features a low-EMI Rabbit 3000-based CPU subsystem running at 29.4 MHz, with 512K Flash / 512K
SRAM or 256K Flash / 256K SRAM, 5 serial ports, and 8 channels of programmable gain analog input in an extremely small footprint
(1.37" × 1.16" / 34 × 29 mm). The RCM3400 comes with a pre-assigned MAC I.D. to be Ethernet ready and the development board
features 10/100Base-T Ethernet and can be used as a reference design in conjunction with Dynamic C's royalty-free TCP/IP software
libraries. Extensive demo programs and software application templates make it easy to get the RCM3400 up and running in record
time.
RabbitCores mount directly on a user-designed motherboard and can interface with all manner of CMOS-compatible digital devices.
Two 34-pin connectors route 47 digital I/O (shared with serial ports), power, and other signals to the motherboard. Built-in low-EMI
features, including a clock spectrum spreader, practically eliminate EMI problems, helping OEMs pass CE and regulatory RF emissions
tests.
The RCM3400 is equipped with 5 V tolerant I/O, quadrature encoder inputs, PWM outputs, and pulse capture and measurement
capabilities. The RCM3400 also features a battery-backable real-time clock, glueless memory and I/O interfacing, and low-power
“sleepy” modes. A fully enabled 8-bit slave port permits easy master-slave interfacing with another processor-based system, and an
alternate I/O bus can be configured for 8 data lines and 6 address lines (shared with parallel I/O).
Programmed with Dynamic C, the RCM3400 executes math, logic, and I/O exceptionally quickly. The Rabbit 3000 chip, RCM3400, and
Dynamic C were designed in a complementary fashion for maximum performance and ease of use in embedded systems. Our
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.
