Microchip Technology AT88SC3216C-PU

Description

The AT88SC3216C member of the CryptoMemory® family is a high-performance secure memory providing 32 Kbits of user memory with advanced security and cryptographic features built in. The user memory is divided into 16 256-byte zones, each of which may be individually set with different security access rights or effectively combined together to provide space for 1 to 16 data files.
