In addition to onboard Wi-Fi/802.11b functionality, the RCM4400W model has a Rabbit
4000 microprocessor operating at 58.98 MHz, static RAM, flash memory, two clocks
(main oscillator and timekeeping), and the circuitry necessary for reset and management
of battery backup of the Rabbit 4000’s internal real-time clock and the static RAM. One
50-pin header brings out the Rabbit 4000 I/O bus lines, parallel ports, and serial ports.
The RCM4400W series receives its +3.3 V power from the customer-supplied mother-
board on which it is mounted. The RCM4400W series can interface with many CMOS-
compatible digital devices through the motherboard.
OEM User’s Manual
The RCM4400W RabbitCore modules adds Wi-Fi/802.11b func-
tionality to the existing Rabbit
allow you to create a low-cost, low-power, embedded wireless
control and communications solution for your embedded control
system. The Rabbit
ware DMA, clock speeds of up to 60 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 than 500 new
opcode instructions that help to reduce code size and improve
processing speed, this equates to a core module that is fast, effi-
cient, and the ideal solution for a wide range of wireless embed-
ded 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 RCM4400W RabbitCore modules and to
prototype circuits that interface to the RCM4400W modules.
You will also be able to write and test software for these modules.
