Secure MCU offers flexible Flash alternative

Flash-based secure microcontroller targets applications that require high computing power, high-speed communication interfaces and seamless connection to very large memories.

New from Atmel, the AT91SC192192CT-USB is a Flash-based ARM SC100 powered secure microcontroller.

The AT91SC series is a family of low-power high-performance 32bit RISC secure microcontroller with ROM or Flash program memory, advanced EEPROM data memory and powerful cryptographic accelerators.

These products target 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 192Kbyte of Flash program memory, 192Kbyte of high-performance EEPROM (fast erase/write time, high endurance) and 24Kbyte 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 particularly well 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 ISO7816 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.

Eric Le Cocquen, Atmel's Embedded Systems Product Line Manager says: "Our new AT91SC192192CT-USB combines Atmel's recognised smart card chip security, state of the art crypto and ARM SC100 computing power with Flash flexibility on a versatile platform designed to address a wide spectrum of security applications".

"Thanks to its rich set of interfaces and Flash, our product can quickly be added to virtually any embedded system".

AT91SC192192CT-USB samples are available now in LQFP64 packages.

Pricing starts at US $8.84 for 10,000 units.
