• Manufacturer Part Number: sle66c46pe
• Description: Chip Card & Security Ics
• Manufacturer: Infineon Technologies Corporation

General Description
The SLE66C46PE is one member of the improved 66PE-series of Infineon Technologies. This high
performance security 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:

Memory
The SLE66C46PE offers 68 Kbytes of User-ROM, 256 byte internal RAM, 2048 byte XRAM and 8 Kbytes
MicroSlim-EEPROM, to fulfill the requirements of mainly standard GSM an SDA payment 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.
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 16Mbyte. However this feature is only available upon
request and will clearly require a change in the existing tool environment.
Short Product Information
Increased internal clock frequency for maximum performance, e.g. for high performance with max.
frequency in payment applications.
Automatically adjusted frequency for a max. given power consumption, e.g. by GSM or UMTS
requirements.
