Although not very popular here in the Philippines, the Rabbit microcontroller can also function in applications requiring data encryption and transmssion. The RCM4300 development kit can also be used as a webserver. Included in the kit are the following items, RCM4300 RabbitCore® module with a miniSD™ card, prototyping board, and Dynamic C® integrated development software with integrated editor, compiler and in-circuit debugger.

“The RCM4300 RabbitCore Module offers the features and performance to support complex embedded designs such as data encryption, secure data transmission, and web server applications.

The RCM4300 core module provides the capability to use up to 1GB mass storage with the industry-standard miniSD™ memory cards which you can swap with another miniSD card without powering down the module. This gigabyte hot-swapping capability offers a new level of functionality to support data logging and automatic meter reading applications.

In addition to mass storage, the RCM4300 core module offers the designer more than 1MB of SRAM for shared code and data to support algorithmic-intensive applications such as graphics and encryption. This greater code space allows you to transmit data in non-critical secure embedded applications. Now you can log as much as 1GB of data and transmit it using Secure Socket Layer (SSL) or Transport Layer Security (TLS) to protect the integrity and confidentiality of the information. You will also be able to design a graphic user interface to make it easier for an operator to monitor the system.”
