Introduction:FM4442 chip card compatible with SLE4442 cardprovides a security code logic which controls the write/erase access to the memory.The FM 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)Applications: Turnstiles Vender,Parking meters e-Payment Gaming & toys Mobile payment, PayPal, Google Wallet, Ticketing,Point of Sale, Coupons Tour guide,etc
