Chapter 1. Introduction - Rabbit RabbitCore RCM5400W User Manual

The RCM5400W RabbitCore modules use the Wi-Fi/802.11b/g
functionality of the Rabbit
create a low-cost, low-power, embedded wireless control and
communications solution for your embedded control system. The
Rabbit ® 5000 microprocessor features include hardware DMA,
clock speeds of up to 100 MHz, I/O lines shared with up to six
serial ports and four levels of alternate pin functions that include
variable-phase PWM, auxiliary I/O, quadrature decoder, and input
capture. Coupled with more the existing opcode instructions that
help to reduce code size and improve processing speed, this
equates to a core module that is fast, efficient, and the ideal solu-
tion for a wide range of wireless embedded applications.
The Development Kit has the essentials that you need to design
your own wireless microprocessor-based system, and includes a
complete Dynamic C software development system. This Devel-
opment Kit also contains a Prototyping Board that will allow
you to evaluate the RCM5400W RabbitCore modules and to
prototype circuits that interface to the RCM5400W modules.
You will also be able to write and test software for these modules.
Throughout this manual, the term RCM5400W refers to both the RCM5400W and
RCM5450W RabbitCore models unless one model is referred to specifically.
In addition to onboard Wi-Fi/802.11b/g functionality, the RCM5400W has a Rabbit 5000
microprocessor operating at 73.73 MHz, static RAM, flash memories, three clocks (main
oscillator, Wi-Fi oscillator, and timekeeping), and the circuitry necessary for reset and
management of battery backup of the Rabbit 5000's internal real-time clock and the static
RAM. One 50-pin header brings out the Rabbit 5000 I/O bus lines, parallel ports, and
serial ports.
The RCM5400W modules receive their +3.3 V power from the customer-supplied moth-
erboards on which they are mounted. The RCM5400W modules can interface with many
CMOS-compatible digital devices through the motherboard.
