SECURITY CHIPS
PURPOSE
Atmels CryptoMemory is a new
Secure Memory family of products
with memory densities from 1 Kbit
(AT88SC0104C) to 256 Kbits
(AT88SC25616C) for smart card
and embedded applications.
This new family of secure
circuits makes available to the
industry a low cost, high security
chip solution that fills the void
between plain serial EEPROM
memories and microprocessors.
Memory densities from 1 Kbit to
256 Kbits are available now.
AT88SC0104C to
AT88SC25616C
This is the only Secure Memory family of
devices in the industry with mutual
authentication between card and reader, and
data encryption for both synchronous
and asynchronous protocols.
FEATURES
" A Family of Devices with User Memories from 1 Kbit to 256 Kbits (1, 2, 4, 8, 16, 32, 64, 128, 256)
" Symmetrical Dynamic Mutual Authentication, 64-bit Cryptographic Key to Authenticate Reader and Card
" Encrypted Passwords with Attempts Counters, Encrypted with a Different Key for Each Usage
" Stream Encryption Ensures Data Privacy
" Read and Write Encrypted Checksum, Guaranteeing Data Integrity and Authenticity of the Source
" Anti-tearing, Avoids Data Corruption or Recovers Data in Case of Power Loss
" Dual Communication Protocol, ISO 7816-3 Asynchronous T=0 and Synchronous Two-wire
" Can Be Used in Virtually Any Reader
" Devices 32 Kbits and Larger Support ISO 7816-3 PPS Exchange for Communication Speeds
up to 153,600 Band
" 2.7V to 5.5V Operation
SECURITY
The device includes a random generator and a proprietary algorithm similar to DES for
encrypting data, passwords and providing MAC for read and write operations, thus providing data
integrity and certification of data origin. Each device is differentiated from all others after
personalization through a unique identification number and set of secret keys. The device secret
keys are issued from the application secret keys using an encryption algorithm such as DES,
3DES, AES, etc., which is chosen by the issuer. This function is performed outside of the device.
