Hash chip protects IP and batteries
The ISL6296 is billed as the industry's most cost-effective, fixed secret hash engine, authentication IC
Intersil has incorporated its unique Flexihash technology in a stand-alone IC solution specifically designed to protect intellectual property and prevent potentially hazardous situations that could be caused by incorrect use of addon peripheral devices. When used for its intended application, the ISL6296 offers the same level of effectiveness as other significantly more expensive and higher maintenance financial-grade hashing algorithms and authentication schemes.

Video digitiser takes more onboard
Device combines ease of use and high-resolution video performance to create the ideal choice for digitising analogue YPbPr video from HDTV tuners, set-top boxes, SD and HD DVDs
When used with Intersil's battery authentication firmware, the ISL6296 solution offers a simple yet powerful means of verifying the authenticity of a cellphone battery pack.
Device authentication is achieved through a challenge-response authentication scheme customised for low-cost applications where cloning via eavesdropping without knowledge of the device's secret code word is not economically viable.
The ISL6296 has a wide operating voltage range, and is suitable for direct powering from a single-cell Li-ion/Li-poly or a three-cell series NiMH battery pack.
This solution is ideal for battery pack and accessories authentication, including battery charging systems and addon products.
Other potential markets are IP protection of reference designs and authentication of disposable items such as printer cartridges.
The ISL6296 is available now in a 5-pin SOT-23 package in standard lead finish or Pb-free.
The suggested unit price for 1000 piece quantities is $1.05.
