Introduction

The AT88SC3216C is a member of the CryptoMemory family, a high-performance secure memory device offering 32K bits of user memory with advanced built-in security and cryptographic features. The user memory is divided into 16 zones of 256 bytes each, where individual security access conditions can be set per zone, or zones can be effectively combined to provide space for 1 to 16 data files.
