Atmel Corp. rolls a new family of secure MCUs designed for smart objects and systems. The AT90SO family offers a range of interfaces to bring security to various applications including USB e-tokens, femtocells, smart meters, secure data storage, telehealth and gaming platforms. The devices are built around Atmel's secureAVR MCU technology, and are claimed to provide higher level of security, performance and lower power consumption than current offerings in the market.

"Designers continue to demand higher security and cryptography computation for next-generation product designs," said Olivier Debelleix, marketing manager for embedded security, Atmel. "Atmel's new secureAVR SoCs address all these requirements. In addition, these products come with a complete security toolbox that can be easily connected to the designers' systems. This new family of SoC MCU brings the most demanding smart card security to any electronic system."

The AT90SO128, Atmel's first member of this new family, is built around the secureAVR 8-/16bit rapid, low-power RISC architecture with 288Kbyte of ROM, 128Kbyte of EEPROM and 12Kbyte of RAM. These features make the secure SoCs compatible with the most demanding firmware developments. Additionally, all the standard cryptography algorithms (AES, DES/TDES, RSA, ECC) are supported by embedded dedicated accelerators which are compatible with the international computer security certifications Common Criteria EAL4+ and FIPS140-2. This product comes in a variety of interface and peripherals including ISO7816, hi-speed SPI, full-speed USB 2.0, I?C compatible and GPIOs. With the secured real-time clock, all applications are stamped with a reliable time stamping to ensure a reliable time and date indication.

AT90SO128 samples are available now in both SOIC8 and QFN44 packages.
