AE43C

AE43C High Security 16-bit Smart Card Microcontroller Features q 8.5kbytes EEPROM q 64kbytes ROM q 2.5kbytes RAM q 1024-bit Coprocessor Integrated Security Concept (ISC) The AE43C designed under Hitachi’s ISC is ideally suited for high security applications. The ISC means that security is not an add-on feature to standard modules or cores security has been built in from the start forming an integral part of the whole Smart Card design concept. The whole ISC process (secure chip design environment, secured production facilities and secure handling during shipment to the customer) is constantly reviewed in order to maximise the overall security package. All devices of the AE-series will be evaluated and certified by independent evaluation authorities. Many security features such as integrated sensors, distributed layout, Random Number Generation (RNG), Watch Dog Timer (WDT), DES-Engine and power analysis attack protection are all included providing a strong onchip hardware security structure. Uniquely, Hitachi Smart Card devices are fabricated using a Metal Oxide Nitride Oxide Silicon (MONOS) EEPROM structure. MONOS advantages compared to standard EEPROM structures are: high resistance to radiation disturbance; high reliability; and endurance. A high performance Coprocessor is complementary to the design concept ensuring final operating system efficiency, application integrity and performance that meet tomorrow’s needs today. Applications The AE43C fulfils the requirements o...
