Atmel Launches AT90SDC100/104 Dual-Core Secure Microcontrollers For Growing PayTV Market

Atmel's TwinAVR microcontrollers offer two independent cores with central processing unit, memory and peripherals on a single chip, unlike current secure MCUs on the market today that offer a single core.

The Master Core is built around Atmel's 8-/16-bit RISC secureAVR, with 128K ROM, 36K EEPROM and 6K RAM. The Secure Core is built around Atmel's 8-/16-bit RISC secureAVR, with 64K ROM, 18K EEPROM, 6K RAM, AdvXTM Crypto Processor, TDES, AES & AIS31 TRNG. This innovative dual core architecture simplifies the implementation of the RED/BLACK concept of segregation between highly sensitive plaintext data (RED) and encrypted data (BLACK), leading to an easier and faster certification.

As the PayTV conditional access market continues to grow and become more complex, smart card developers demand higher performance and storage capacity while maintaining the highest level of security, said Eric Le Cocquen, Atmel's marketing manager for PayTV products. Atmel's TwinAVR addresses all these issues. Segregation of the RED and BLACK domains traditionally relies on hardware firewalls and a lot of software. The TwinAVR goes one step beyond by offering, on the same chip, a master core to implement the BLACK domain and a secure core to implement the RED domain, thus providing an indisputable segregation between the two domains. The two cores also increase the overall system performance considerably, equaling a 32-bit MCU, while the data flash interface enables large storage capacities. This new family offers a complete solution for smart card developers in the PayTV market.

Atmel's TwinAVR MCU features an ISO 7816-3 smart card interface and a built-in DataFlash® interface. Large amounts of data can be stored with flash die stacking to the microcontroller and by fitting both chips in a standard smart card module. This product meets Common Criteria EAL5+ security certification.
