MICROCHIP AT88SC0404C-MJ

The Atmel AT88SC0404C member of the CryptoMemory family is a high-performance secure memory providing 4-Kbits of user memory with advanced security and cryptographic features built in. The user memory is divided into four 128-byte zones, each of which may be individually set with different security access rights or effectively combined together to provide space for one to four data files.
