RCM5400 Family RabbitCore®

Rabbit Semiconductor and Digi-Key announce RCM5400W and RCM5450W models

RCM5400 Family RabbitCore® The RCM5400W RabbitCore® module series provides Wi-Fi/802.11b/g functionality that enables the creation of low-cost, embedded wireless control, and communications solutions for embedded control applications. RabbitCore modules mount directly onto a user-designed motherboard and act as the controlling microprocessor for the system. Measuring only 1.84" × 2.85" × 0.55" (47 mm × 72 mm × 14 mm), the Rabbit® 5000 microprocessor-based RCM5400W series delivers the capability to integrate real-time control and Wi-Fi connectivity into a design. The Rabbit 5000 delivers the same proven architecture as the industry-proven Rabbit 4000 microprocessor, along with additional features including hardware DMA, higher clock speeds, more I/O lines, six serial ports, and more instructions to reduce code size and improve processing speed.
