The ARMtwister is a small embedded control board with PCMCIA socket utilizing the Atmel AT91M40800 Microcontroller. With its customized version of uClinux-2.4 it is possible to use IEEE 802.11 Wireless PCMCIA cards, as well as Ethernet cards and most other 16-bit PCMCIA cards.

Applications

The board is ideal for developing wireless applications. The onboard flash can be used for data logging systems. The board can be used for development as well as for final products, thereby reducing the effort for hardware development.

Hardware

The DRAM controller and the PCMCIA host controller are implemented in a low-cost PLD, and reduce the cost by saving expensive SRAM as well as a dedicated PCMCIA host controller. The PLD design is available as an optional development kit that makes it easy to jump-start your own embedded design.

In-System Programming

The ARMtwister supports reprogramming of the flash by using a standard 20-pin JTAG header. In addition, PLD firmware upgrades can be done through JTAG.

Software

The uClinux source distribution includes the sources for the tool chain, kernel, a large number of applications and libraries. The web based configuration makes it easy to select and customize the modules that are required by the application. New applications can easily be added to the build system.
