Intersil's FlexiHash+™ Battery Authentication ICs for Cell Phones Provide Low-Cost, Highly-Effective Device Security

Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors has introduced the most advanced and flexible battery authentication ICs for cell phones, featuring the company’s unique FlexiHash™ technology. The new ISL9206 and ISL9206A are cost-competitive battery authentication ICs that incorporate Intersil’s FlexiHash+ engine. It provides very high levels of security using a basic challenge/response scheme based on 32-bit challenge code and 8-bit response code.

— ISL9206 and ISL9206A Feature Next-Generation FlexiHash+™ Engine to Secure Cell Phone Batteries and Replaceable Utilities in Communication, Printing Systems —

FlexiHash+ employs two sets of 32-bit secrets for generating authentication code to offer tens of billions of potential configurations for users. And with 16×8 one-time programmable (OTP) ROM, the devices can store a total of three sets of these 32-bit secrets. The ISL9206/06A can be powered directly from a one-cell li-Ion/li-Polymer or a three-cell series NiMH battery pack.

Both new authentication ICs also include a clone prevention feature offering safety and revenue protection suitable for protection against after-market replacements. As an added feature, the ISL9206 incorporates multi-pass authentication that can be used to maximize security. Both devices are also ideal design choices for a wide variety of printer cartridges.
