Atmel ATAES132
CryptoAuthentication family of hardware
security solutions
The Atmel® ATAES132 is the latest member of the CryptoAuthentication™ family of secure authentication devices, and utilizes
an AES-128 cryptographic engine to provide both authentication and confidential, nonvolatile data storage. The ATAES132
is pin-out and instruction set compatible with standard SPI and I²C serial EEPROMs, allowing system designers to quickly and
cost-effectively add security functionality to their products. The 32-Kbit EEPROM is segmented into sixteen user zones, with
access permissions independently configured, as well as sixteen 128-bit keys, which can be used with any zone. These keys
can also be used for standalone authentication. This key management flexibility makes the ATAES132 ideal for a wide variety
of applications. The ATAES132 incorporates multiple physical security mechanisms to prevent release of the internally stored
secrets, as well as secure personalization features to facilitate third-party product manufacturing.

Atmel ATAES132
CryptoAuthentication family of hardware
security solutions
Integrating hardware security into embedded systems has never been easier than with the Atmel® CryptoAuthentication™
family of hardware security solutions. Multiple evaluation and development support tools are available for the Atmel
ATAES132, giving designers the necessary flexibility to meet the most aggressive development timelines. To gain a
basic understanding of the Atmel ATAES132 device architecture and capabilities, the very low-cost AT88CK427GREEN
demonstration kit is a great choice. For more comprehensive evaluation and development capabilities, designers can choose
from client or client and host kit configurations that include USB connectivity as well as a modular hardware design approach
that enables rapid and easy development in most development environments. Additionally, the Atmel ATAVRSECURITYX
Security Xplained add-on board for the Atmel AVR® Xplained development platform provides a seamless avenue to
integrate security into your embedded application. All Atmel ATAES132 tools are based on Atmel AVR devices, with
software and libraries available at www.atmel.com.
