SAM7 Microcontroller module eNet-sam7X

The eNet-sam7X module was designed as easy drop-in ARM7 module and allows you a money and time saving integration of ethernet and usb interfaces along with a powerfull SAM7 microcontroller into your project.
Versatile interfacing options will meet all your needs. The integrated Micro-SD slot allows easy memory extension and makes the module the ideal solution for data logging, control and measurement tasks. Using the embedded webserver option allows an easy integration of modern user interfaces into your device.
Data encryption is very important in the industrial context. The integrated hardware encryption acceleration for AES and 3DES encryption makes the eNet-sam7X module the ideal solution for security appliances.
The module is designed as 64 pin DIP module which allows easy drop-in into every application. All unused processor signals are available at pin headers and may be used freely.

The module is available in two assembly variants (Basic, PRO). For details see the "Ordering information".

Please note: Newer Linux kernel versions (since 2.6.34) which are used by modern Linux distributions like Ubuntu 10.10 (Maverick) does not support the Atmel SAM-BA protocol any more (caused by a kernel bug). For these Linux versions we offer a special Atmel SAM-BA usb driver kernel module. This driver was developed by Johan Hovold an will be probably included in one of the next mainline Linux kernel versions.
