TI previews MSP430FR59xx low power MCUs

Posted on Thursday, November 15th, 2012 in components, MSP430, News by the machinegeek

TI has announced the preview of the MSP430FR58xx and MSP430FR59xx family of ultra-low-power microcontrollers. This group consists of several devices featuring embedded FRAM nonvolatile memory, an ultra-low-power 16-bit MSP430 CPU, and different sets of peripherals targeted for various applications. The architecture, FRAM, and peripherals, combined with seven low-power modes, are optimized to achieve extended battery life in portable and wireless sensing applications. FRAM is a new nonvolatile memory that combines the speed, flexibility, and endurance of SRAM with the stability and reliability of flash, all at lower total power consumption.

The MSP430FR59xx devices provide an 256-bit AES security encryption and decryption coprocessor.

MSP430FR58xx devices do not provide AES encryption and decryption in hardware.

You can download the 81 page PDF here, and TI says while components are not in stock they are taking requests for samples to be sent at a later date.

    Hmmm… On-die AES 256 perhaps? Unless you are trying to comply with bloated Government Specs, maybe it would be better to try Elliptic-Curve Crypto instead. I’d like to see a comparison between EC crypto in clock optimized ASM code vs. native AES 256 on this part.

    If there are any crypto experts out there, chime in. I really don’t have a handle on the trade-offs with EC vs. AES, especially when there is AES hardware on the die with this part. Good chance I’m off the mark…

    AES is symetric (shared key) crypto, EC is asymetric. With EC you get lots of export control issues.

    Er… Crypto export restrictions in the U.S. were seriously relaxed back in 2000. I believe today you there are essentially no restrictions as long as you are not exporting to a end-user that is a Governmental entity or to a handful of countries that you would most likely not want to mess with in the first place. Prior to 2000 export of EC crypto was limited to 112 bit keys maximum. Go to the RSA Labs site and search for “United States Cryptography Export/Import” for details.

    A bigger issue with EC and HEC is patents. The main corpus of EC crypto theory is essentially not burdened by patents, but many if not most implementations (especially the efficient ones) are burdened by patents. Certicom (now owned by Research in Motion – yeah the Blackberry loons) owns many of the EC field patents.
