1 / 2 page  AE45C High Security 16-bit Smart Card Microcontroller Features 32.5Kbytes EEPROM 96Kbytes ROM 4.5Kbytes RAM 1024-bit Coprocessor Integrated Security Concept (ISC) Applications The AE45C designed under Renesas Technology ’ s ISC is ideally suited for high security applications. The ISC means that security is not an add-on feature to standard modules or coressecurity 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. The AE45C has been certified under the Common Criteria to EAL4+ using Protection Profile BSI-PP- 0002-2001. 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 on- chip hardware security structure. The AE45C fulfils the requirements of Smart Card applications requiring large memory, high security and high speed secure authentication, data encryption or electronic signature. Examples include: Public Key Infrastructure (PKI), Wireless Application Protocol (WAP), m-commerce, digital signature, and USIM/UMTS. Where PKI is a core requirement, a high speed Coprocessor is needed that can process arithmetical data in a time frame that ensures a fast and free flowing application environment. The AE45C Coprocessor ensures the high performance required by today’s high security applications. The move from single to multi-application on a single component is also rising due in part to new systems such as WAP and m-commerce. This requires not only additional memory for application data storage but also features such as Firewall Management Units (FMU) in order to provide data integrity between applications. Applications such as WAP and m-commerce are continually expanding in scope and consequently the need for greater memory storage for both data and program code is constantly increasing. The AE45C provides a significant increase in ROM for program storage over previous devices whilst ensuring a balance of EEPROM for data storage. Uniquely, Renesas Smart Card devices are fabricated using a MONOS (Metal Oxide Nitride Oxide Silicon) 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. |
