SLE 88CFX4000P
Peripherals
A number of powerful peripherals offer hardware support for time and code intensive operations.
The Crypto@1408Bit is equipped with its own RAM of 880 bytes and supports all of the known
public-key algorithms based on large integer modular arithmetic with configurable register lengths
of up to 1408 bits. It allows fast and efficient calculation of e.g. RSA operations with key lengths up
to 2048 bit but also Elliptic Curves over GF(p) as well as GF(2^m). A 1024-bit RSA signature with
Chinese Remainder Theorem can be performed in 4ms at 66MHz. For symmetric crypto
operations, a DES accelerator supporting also Triple-DES is implemented. A Triple-DES can be
performed in 1.5 microseconds at 66MHz. Using the Crypto@1408Bit and DES module a secure
transmission for downloading of additional applications can be ensured.
The UART supports the chip card protocols T=0 and T=1 and is also able to manage full-duplex
data transfer.
The True Random Number Generator (TRNG) is able to supply the CPU with true random
numbers whose quality is ensured according to AIS-31 strict evaluation guidelines.
An interrupt control unit supports a programmable interrupt system with UART, timers, and the
other peripherals as interrupt sources.
A variety of different trap vectors informs the operating system about exceptions (e.g. access
violation).
Security
As security is Infineon first priority, an innovative security concept has been created that is based
on the entire integration of security measures in the SLE88 at each design phase of the core,
architecture and modules, at every level, and does not exclusively rely on the addition of security
features to an existing system. With this Integral Security Concept, the SLE 88 takes a quantum
leap in terms of improved on-chip security. Targeted certification is Common Criteria level EAL5+.
Support
A broad range of hardware and software based development tools offers to the user the facilities
for high-end operating system development and validation. The PSL provides all devices drivers
necessary to use the chip resources and peripherals such as optimum EEPROM programming,
memory management, crypto implementations, and many others. It also allows an easier and
faster code implementation on a high level, without detailed knowledge of the hardware, and
independently of its eventual changes and evolutions. As a consequence, porting an existing code
from a derivative of the SLE88 family to the other is easy and quick.
Conclusion
SLE 88CFX4000P fully meets the requirements for real multi-application operating systems. It
allows secure operation of banking, access control, loyalty, GSM/USIM, Pay-TV, health care and
identification applications all in one chip. The advanced 0.13 micron technology, the Integral
Security Concept, the low power optimised 32-bit core supported by various powerful peripherals,
and the possibility to adapt the performance to application requirements establish the foundation
for a completely new chip card era.
