General Description

SLE 22C05S is a member of the Infineon Technologies low cost security controller family in 0.6 μm CMOS technology. The 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.

The controller IC offers 7.5 Kbytes of User-ROM, 128 bytes internal RAM and 512 Bytes EEPROM.

The CRC module allows the easy generation of checksums according to ISO 3309 (16-BitCRC). To minimize the overall power consumption, the chip card controller IC offers a sleep mode.
