General Description
The SLE66C24PE is a 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 SLE66C24PE offers 68 Kbytes of User-ROM, 256 Bytes internal RAM, 2048 byte XRAM and 2 Kbytes
MicroSlim-EEPROM, to fulfill the requirements of mainly SDA payment, Identification and loyalty 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.
In addition, new instructions have been implemented in the design for an efficient direct access of physical memory
>64Kbyte up to 16 MByte.
Preliminary - 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.
