Atmel has expanded its CryptoMemory family of 1 to 16 Kb devices to include higher densities of 32 through 256 Kb of memory. This high density range of ICs gives customers many of the same security features found in microprocessor-based systems. Because this solution does not require the added expense of an operating system or programming resources, these products are low-cost and faster to market.
These devices are suited in applications such as driver's licences and healthcare cards to securely store sensitive data. CryptoMemory is also a secure drop-in solution to improve on traditional serial interface EEPROMs in embedded applications, such as authentication of OEM subassemblies, including removable storage devices and automotive piece parts.
"These new high density products enable Atmel to compete in smartcard and embedded markets, such as government healthcare cards or secure access applications, which have previously relied on expensive microcontrollers," said Kerry Maletsky of Atmel. "Atmel is the only semiconductor manufacturer to provide a full range of security products that includes everything from serial EEPROMs to crypto processors. This high density CryptoMemory family of circuits provides a secure yet inexpensive solution for everyday applications."
CryptoMemory is a low-cost, high security family of memory chips with on-chip hardware data encryption including both synchronous and asynchronous protocols. It is compliant to the smartcard ISO7816-3 standard using T=0 protocol, the same protocol used in secure microprocessors, allowing it to function in virtually all smartcard readers. Additionally, its 2-wire protocol allows for faster personalisation in smartcards and also enables a board designer to secure data in non-volatile memory.
