The RCM4400W RabbitCore modules adds Wi-Fi/802.11 functionality to existing Rabbit® 4000 microprocessor features, allowing you to create a low-cost, low-power, Wi-Fi based control and communications solution for your embedded system.

The RCM4400W RabbitCore modules are equipped with on-board Wi-Fi/802.11 wireless connectivity. Features also include 512K flash memory and fast-program execution SRAM, 35 general-purpose I/O, 3.3 V I/O line, and low-power modes.

At the heart of the RCM4400W is the Rabbit 4000 microprocessor which features a clock speed of up to 58.98 MHz. Other features include hardware DMA, auxiliary I/O, quadrature decoder, input capture, GPIO lines shared with up to six serial ports, and four levels of alternate pin functions that include variable phase PWM. The Rabbit 4000 boasts an additional 500+ new operational code instructions that increases the processing efficiency, from its predecessor the Rabbit 3000.

The RCM4400W RabbitCore modules are easily interchangeable with other RCM4xxx based products due to electrical and functional compatibility. With a small footprint of 1.84”x2.85” (47mm x 72mm), the RCM4400 is compact and can easily be mounted directly onto a user-designed motherboard, along with CMOS-compatible digital devices.
