General Description

SLE 44C24S is a member of the Infineon Technologies security controller family produced

in 0.6 µm CMOS technology. The CPU provides the high efficiency of the SAB 8051

instruction set together with enhanced performance and a new level of security features.

The controller IC offers 24 Kbytes of User-ROM, 256 bytes internal RAM, 512 bytes XRAM

and 2 Kbytes EEPROM. To minimize the overall power consumption, the chip card

controller IC offers a sleep mode.

SLE 44C24S offers high performance and large memory sizes combined with outstanding

security features on a minimized chip size. Therefore the device fulfills all chip card

requirements and is especially well fitting for payment, loyalty, health care and access

control.
