SLE4404

The SLE4404 contains an EEPROM and security logic. The memory area includes a 416 memory cell matrix organized in 16-bit rows. The device is ideally suited for security applications, such as personal or transferable cards in all counting and calculating systems, in all credit and debit systems and used as electronic key.

There are some features SLE4404 as follows: (1)416*1 bit organization; (2)208-bit user memory which can be configured as ROM, PROM, read-protected PROM and read-protected ROM; (3)user memory protected by means of a changeable user code with non-volatile error counter (blocking state after four incorrect inputs); (4)user memory reloadable and configuration changeable up to 64 times, protected by unchangeable memory code with non-volatile counter; (5)7 additional memory areas with special characteristics; (6)minimum of 104 write/erase cycles; (7)data rentention for a minimum of 10 years; (8)PIN security logic and other special security features.

The following is about the maximum ratings SLE4404: (1)supply voltage, VCC: -0.3 to 6 V; (2)input voltage, VI: -0.3 to 6 V; (3)storage temperature, Tstg: -40 to 125; (4)power dissipation, Ptot: 50 mW. Then is about the operating range: (1)supply voltage, VCC: 4.75 V min and 5.25 V max; (2)ambient temperature, TA: -35 to 80.
