Atmel Corp. launches the AT91SC192192CT-USB, a flash-based, ARM SC100 powered, secure MCU. The AT91SC series is a family of low power, high-performance 32-bit RISC secure MCU with ROM or flash program memory, advanced EEPROM data memory and powerful cryptographic accelerators. The product targets applications that require high computing power, high-speed communication interfaces and seamless connection to very large memories.

Based on the ARM SC100 CPU, the AT91SC192192CT-USB features 192Kbytes of flash program memory, 192Kbytes of high-performance EEPROM (fast erase/write time, high endurance) and 24Kbytes of RAM. Also included are a Full Speed USB 2.0 interface with five Endpoints, an SPI interface to communicate in an embedded system environment or to connect to a NOR flash and dedicated hardware to connect to a NAND flash. The device is suited to build high-end secure e-Tokens and to be used in embedded systems where it can serve as a security module to prevent hardware counterfeiting, store secure data, provide authentication services, process digital rights management etc.

Fully compatible with the ROM-based AT91SC512384RCT, the AT91SC192192CT-USB also incorporates the standard ISO 7816 smart card and the emerging single wire protocol (SWP) interfaces. This makes the AT91SC192192CT-USB a flexible flash alternative to its ROM sibling for Smart Card applications such as next-generation (U)SIM cards.

AT91SC192192CT-USB samples are available now in a LQFP64 package. Pricing starts at $8.84 for 10,000 units.
