Rabbit Goes Wireless

April 10, 2007

Integrated Wi-Fi and ZigBee are the Latest Additions to the
Popular Family of Pin-compatible RabbitCore Modules

    DAVIS, Calif. April 10 /Xinhua-PRNewswire/ -- Rabbit
Semiconductor is boldly going wireless by offering two new
wireless technologies directly integrated in new
RabbitCore(R) modules.  Customers can now connect their
products to the Internet and network their devices without
wiring headaches. The new RCM4400W is a Wi-Fi/802.11 based
core module that leverages the increasing penetration of
Wi-Fi in businesses around the world.  The RCM4510W is a
ZigBee/802.15.4 based module that taps into the exciting,
high growth ZigBee market for low cost, low power wireless
sensor networks.  These modules add to the powerful list of
embedded control features that have made RabbitCore modules
so appealing to design engineers around the world. 

    These wireless solutions have been engineered into the
Rabbit product line as part of a fundamental goal to
provide easy-to-use connectivity built upon proven
platforms that can accommodate the typically long embedded
product life cycles.  The RCM4400W and RCM4510W expand on
the family of pin-compatible modules already based on the
Rabbit 4000 microprocessor, giving customers greater
freedom to now select from serial, wired Ethernet, wireless
Ethernet / Wi-Fi or wireless ZigBee / 802.15.4 as their
communication link in their Industrial Control, RTU or
Building Automation applications. 

    The RCM4400W features Wi-Fi / 802.11 connectivity and
is powered by the Rabbit(R) 4000 microprocessor, running at
58.98 MHz.  Features include up to 35 GPIO lines shared with
6 serial ports, hardware DMA, quadrature decoders, PWM, and
up to four levels of alternate pin functions. The RCM4400W
supports an operating temperature range of -20¡ãC to
+85¡ãC. 

    The RCM4510W features ZigBee/802.15.4 connectivity and
uses MaxStream(R) technology with the integration of the
XBee Series 2 ZigBee module as part of the RabbitCore
design.  It is also powered by the Rabbit 4000 running at
29.49 MHz. Features include up to 49 GPIO lines shared with
6 serial ports and 4 channels of analog inputs, hardware
DMA, quadrature decoders, PWM, and up to four levels of
alternate pin functions. The RCM4510W supports an operating
temperature range of -40¡ãC to +85¡ãC.  

    Because the RCM4400W and the RCM4510W are designed to
be electrically pin-compatible with all other Rabbit
4000-based RabbitCore modules, engineers can support
numerous applications with the same motherboard design by
simply changing the RabbitCore module to meet each
application's specific requirement.   

    Development Kits for the RCM4400W and RCM4510W are
immediately available for shipment.  Each contains the
appropriate full-featured wireless RabbitCore, a
development board, the latest Dynamic C integrated
development software with hundreds of samples and
libraries, and all the accessories that are needed for a
quick start on development.  The RCM4400W module is priced
at $99/Qty100, the RCM4510 is priced at $72/Qty 100.  Both
the RCM4400W Development Kit and RCM4510W Development Kit
are available for a limited time at $199 each.
