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".

|Bootloader||Mask-programmed USB bootloader. Further bootloaders (e.g. TFTP, x/y modem, etc.) are available|
|Programming / Debugging||JTAG interface for programming and in-system debugging|
|Voltage regulator||Optional: 3.3V Switching regulator on board|
|Dimensions||DIP 64 format, 27 mm x 8 mm x 82 mm (W x H x L, without pin-header, with voltage regulator)|

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.
|Ordering code ||Description|
|eNet-sam7X - Basic||Only bottom side populated. Without Micro-SD slot, without USB connector and without integrated voltage regulator. External 3.3V powering is needed|
|eNet-sam7X - PRO||Fully mounted with Dataflash, USB connector, with Micro-SD slot and integrated 3.3V switching voltage regulator|
