General Description
SLE 44C80S is a member of the Infineon Technologies 44 security microcontroller family,
especially designed for smart card applications. The device is fabricated in an Infineon
Technologies proprietary CMOS technology, resulting in a significant reduction of die size
compared to the SLE 44C80S. 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, payment, pay-TV or security access while maintaining software
compatibility to the SLE 44C80S manufactured in the previous technology.
