Introduction:

SLE4442 provides a security code logic which controls the write/erase access to the memory. 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.

Features:

● Byte-wise addressing
● Irreversible byte-wise write protection of lowest 32 addresses (Byte 0 ... 31)
● 32 × 1-bit organization of protection memory
● Two-wire link protocol
● End of processing indicated at data output
● Answer-to-Reset acc. to ISO standard 7816-3
● Programming time 2.5 ms per byte for both erasing and writing
● Minimum of 104 write/erase cycles1)
● Data retention for minimum of ten years1)
● Contact configuration and serial interface in accordance with ISO standard 7816 (synchronous transmission)
