Unsurpassed Computing Power and Leading-Edge Security Capability for Multi-Application Chip Cards: Infineon Technologies Introduces 32-bit Chip Card Controller Family
The first IC in the 88 family, the SLE88CX720P, sets a new standard in performance and flexibility for chip card controllers. It optimally meets customer requirements for large fixed and re-programmable memory, Virtual Machine Language acceleration to execute application code written in JavaSC and other stack-oriented languages. Simplified software development facilitates faster time-to-market, and exceptional security functionality adds further customer benefits. The IC is based on a 32-bit RISC CPU running at frequencies of up to 66 MHz. This provides the performance headroom needed to assure that card suppliers investments in software development can be deployed across a wide range of current and future systems.
The chip card industry seeks to provide systems supporting robust and secure high-performance applications in the fast growing financial services and mobile communications markets. These performance requirements surpass the capability of current 16-bit architecture products, said Dr. Hermann Eul, senior vice president and general manager of the Security & Chip Card IC Business Group of Infineon Technologies. Building on the advantages of our unique system-on-chip design capability and efficient manufacturing processes, we are able to deliver true 32-bit performance and on-chip memory exceeding competitive offerings, at just a small cost premium compared to 16-bit alternatives.
The 88 family is based on a workstation-like core architecture, incorporating on-chip data and instruction caches to support fast program execution by pre-fetching instructions. It accelerates all Virtual Machine-based chip card languages, including JavaSC, MultOS and Windows Powered Smart Cards. The chip architecture also is optimized to run multiple tasks in parallel, including peripheral functions such as external communications through the on-chip UART and execution of data encryption and security functions.
To meet requirements for the highest possible security, the 88 familys integral security concept combines multiple levels of physical protection and encryption support, including the industrys strongest DPA/SPA (Differential Power Analysis/Simple Power Analysis) countermeasures. The on-chip Memory Management Unit (MMU) incorporates hardware firewalls to isolate and protect applet code from other system elements. In order to support symmetric and asymmetric algorithms, the controller features powerful crypto coprocessors with highest performance for DES (Data Encryption Standard), Triple-DES, RSA (Rivest, Shamir, Adleman) and elliptic curves algorithms. RSA algorithms with key lengths of 1.024 bits are processed in 65 milliseconds without Chinese Remainder Theorem (CRT).
To reduce card suppliers development costs and speed time-to-market, Infineon also provides a Platform Support Layer (PSL), which is a complete set of low-level drivers for all peripherals and a crypto library for RSA, elliptic curves and AES (Advanced Encryption Standard).
Additional members of the 88 family will be announced in 2002.
Technical information on SLE88CX720P
The first member of the 88 family, the SLE88CX720P, includes 240 Kbytes of ROM, 80 Kbytes of EEPROM, 8 Kbytes of RAM, a crypto coprocessor, and UART with two I/Os. It operates at a voltage range of 1.8 to 5.0 V, in full compliance with ETSI specifications.
Engineering samples of the SLE88CX720P will be available in December 2001 with volume production planned in Q1 2002. The product is shipped as sawn wafers or packaged in modules.
The SLE88CX720P is one of the three projects nominated for the prestigious SESAMES award in the category Best Technological Innovation. Every year at Cartes show, this award is presented to honor technical achievement and innovation within the card industry and card-related industry.
Infineon will be present at Cartes 2001 show (23.-25. October 2001, Paris, France) at booth U44 in Hall Curie.
