General Description
The MAXQ1103 microcontroller is a low-power, 32-bit RISC device that combines high-performance, single cycle processing, sophisticated tamper-detection technology, and cryptographic hardware. Advanced security features are designed to meet the stringent requirements of regulations such as ITSEC E3 High, FIPS 140-2 Level 3, and the Common Criteria
Certifications. The MAXQ1103 is targeted at electronic commerce, banking, and data security systems that require the highest levels of secure access control, secure data storage, digital signature, or certificate authentication. A secure memory protection unit protects critical internal and external memory against tampering with triple-DES (3DES) encryption. Activation of a tamper sensor causes a rapid zeroization of critical data. An internal physical shield layer increases the complexity and cost of a physical attack against the die.
