SLE4442

SLE4442 Contact Chip Memory Card featuring 256 Bytes, Contact Configuration, and Serial Interface compliant with ISO 7816 Standard (Synchronous Transmission)

Contact Chip Memory Card 256 Bytes, Contact Configuration, and Serial Interface compliant with ISO 7816 Standard (Synchronous Transmission)

Provides a security code logic which controls the write/erase access to the memory.

For this purpose the chip contains a 4-byte security memory with an Error Counter EC (bit 0 to bit 2) and 3 bytes reference data.

These 3 bytes as a whole are called Programmable Security Code (PSC).

After power on the whole memory, except for the reference data, can only be read.

Only after a successful comparison of verification data with the internal reference data the memory has the identical access functionality of the SLE 4432 until the power is switched off.

After three successive unsuccessful comparisons the Error Counter blocks any subsequent attempt, and hence any possibility to write and erase
