THE A31-μQ7 MODULE PROVIDES A SOLUTION to build custom devices with a tablet-class processor. With the module, users can realize their design powered by a quad-core Cortex-A7 (running at up to 1,2 GHz), up to 2 GiB of DDR3, HDMI, dual-channel LVDS, Gigabit Ethernet, SATA, 8 USB 2.0 ports, and a dedicated CAN co-processor.

With the increasing importance of networked and connected applications, new security challenges have arrived. The secure identification of individual field-deployed devices, secure key storage, and the establishment of secure communication channels are requirements in many applications. The A31-μQ7 module offers a solution by integrating an advanced security module from STMicroelectronics.

The smart-card silicon and the operating system are compliant to the Java Card 2.2 and Global Platform 2.2.1 specifications. Active and passive countermeasures to physical tampering and data extraction are included, as well as differential power analysis (DPA) and differential fault analysis (DFA) countermeasures against side channel attacks. The module also supports cryptosystems based on both RSA and ECC algorithms. Support for the security module is available in the board-support package for the A31-μQ7 module.

A Mini-ITX baseboard, suitable for ARM-based Qseven and μQseven modules, is available for evaluation and development purposes. The baseboard can be used as a reference design.
