1. I
NTRODUCTION
The RCM5700 and RCM6700 are compact modules in a mini PCI Express form factor, and incor-
porate the powerful Rabbit
®
5000 and 6000 microprocessors with integrated 10/100Base-T Ether-
net functionality and onchip SRAM. The Rabbit® 5000 and 6000 microprocessor features include
hardware DMA, I/O lines shared with up to six serial ports and four levels of alternate pin func-
tions that include variable-phase PWM, an external I/O bus, quadrature decoder, and input cap-
ture. This equates to a MiniCore module that is fast, efficient, and the ideal solution for a wide
range of embedded applications.
Development Kits are available with the essentials that you need to design your own microproces-
sor-based system, and includes a complete Dynamic C software development system. The Devel-
opment Kit also contains an Interface Board with USB and Ethernet connections that will allow
you to evaluate the RCM5700 or RCM6700, and a Prototyping Board to help you to develop your
own applications. You will also be able to write and test software for the RCM5700/RCM6700
modules, including Ethernet applications.
The RCM5700 has a Rabbit 5000 microprocessor operating at up to 50.0 MHz, flash memory,
two clocks (main oscillator and real-time clock), and the circuitry necessary to reset and manage
the Rabbit 5000. The RCM6700 has a Rabbit 6000 processor operating at up to 187.5 MHz and
1MB of internal SRAM. An edge connector brings out the MiniCore module user interface to a
52-pin mini PCI Express socket on the motherboard the core module is mounted on.
The RCM5700/RCM6700 receives its +3.3 V power from the motherboard on which it is
mounted. The MiniCore module can interface with other CMOS-compatible digital devices
through the motherboard.
