1.256 * 8-bit EEPROM organization 2.Answer-to-Reset acc. to ISO standard 7816-3 3.Minimum of 104 write/erase cycles

Overview:

As we all know, SLE4442 is the most common chip that used in security area. The striking advantages are stable function and the most cost-efficient price! Of course, RealSmart is the giant player for such chips! Except the above advantages, fast delivery, strong package etc. always is our duties!

General Description:

SLE 4442 provides a security code logic which controls the write/erase access to the memory. For this purpose the SLE 4442 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.
