SLE66C161PE

The  SLE66C161PE is a member of the improved 66PE-series of Infineon Technologies and the successor of the
SLE66C162P. 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: 
·  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. 

Memory: The SLE66C161PE offers 48 Kbytes of User-ROM, 256 byte internal RAM, 2048 byte XRAM and 16 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. 16kByte of EEPROM thus allows to
include  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.
