SLE 66C681PE
General Description
The SLE66C681PE is another member of the improved 66PE-series of Infineon Technologies and the
successor of the SLE66C640P. This high performance security crypto controller is manufactured in
advanced 0.22 µm CMOS technology. It is downward compatible to existing 66P controller derivatives. The
well known ECO2000 8/16 bit CPU provides the high efficiency of the SAB 8051 instruction set extended by
additional powerful instructions together with enhanced performance, memory sizes and security features
compared to existing 66P derivatives.
Performance: The internal clock frequency can be adjusted to a level up to 33 MHz either as a multiple of
1,2,3,4 to the external frequency or independent of the clock rate of the terminal with the help of the internal
clock. It is adjustable according to either available power requirements or required performance:
• Increased internal clock frequency for maximum performance, e.g. for high performance with max.
frequency in payment applications or crypto operations.
• Automatically adjusted frequency for a max. given power consumption, e.g. by GSM or UMTS
requirements.
Memory: The SLE66C681PE offers 136 Kbytes of User-ROM, 256 byte internal RAM, 4352 byte XRAM and
New
68 Kbytes MicroSlim-EEPROM, to fulfill the increased requirements of GSM and UMTS applications. The
large ROM size allows to place applications in the ROM-mask and to keep the E²PROM free for customer
data. In addition it saves mask development costs, as one mask may be used for different customer projects.
68 Kbyte of EEPROM thus allows to include SIM Application Toolkit, Wireless Application Protocol (WAP),
WML-Browser and JavaCard API implementations into the NVM.
The enhanced Memory Management and Protection Unit allows a secure separation of the operating system
and different applications. It allows to separate the memories in application orientated segments, which can
be controlled by the OS. Furthermore, the MMU makes a secure downloading of applications possible even
after personalization of a card. These new features suit the requirements of the next generation of multi
application operating systems.

The new platform is designed to address up to 16 Mbyte. However this feature is only available upon request
and will clearly require a change in the existing tool environment.
In addition, new instructions have been implemented in the design for an efficient direct access of physical
memory >64Kbyte up to 16 Mbyte.
