General Description SLE 44C42S is a member of the Infineon Technologies 44 security microcontroller family, especially designed for smart card applications. The devices fabricated in an Infineon Technologies proprietary CMOS technology, resulting in a significant reduction of die size compared to the SLE 44C40. New features such as low voltage operation, extended page mode and I/O routines offer additional performance required in applications like 3V SIM cards for GSM, banking, health care, security access or loyalty, while maintaining software compatibility to the SLE 44C40.
