Intersil's FlexiHash+(TM) Battery Authentication ICs for Cell Phones Provide Low-Cost, Highly-Effective Device Security
ISL9206 and ISL9206A Feature Next-Generation FlexiHash+(TM) Engine to Secure Cell Phone Batteries and Replaceable Utilities in Communication, Printing Systems
MILPITAS, CA, March 20, 2008 - Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today introduced the most advanced and flexible battery authentication ICs for cell phones, featuring the company's unique FlexiHash(TM) 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.
FlexiHash+ employs two sets of 32-bit secrets for generating authentication code to offer tens of billions of potential configurations for users. And with 16x8 one-time programmable (OTP) ROM, the devices can store a total of three sets of these 32-bit secrets.
Programmable memory adds the ability to store up to 48 bits of ID code and/or pack information. The result is fast, highly secure and flexible battery/device authentication that makes hacking prohibitively difficult due to the exhaustive key search that would be needed to break a code.
The ISL9206/06A each have an operating voltage range from 2.6V to 4.8V and can be powered directly from a one-cell li-Ion/li-Polymer or a three-cell series NiMH battery pack. The devices can also be powered by the XSD bus when the bus pull-up voltage is 3.3V or higher. They connect to the cell terminals of a battery pack and include an on-chip voltage regulation circuit, POR and a non-crystal based oscillator for bus timing reference.
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.
Pricing and Availability
The ISL9206 and ISL9206A are available now in space-saving 5 Ld SOT-23 and 8 Ld TDFN packages and are priced at $1.40 and $1.73 each, respectively, in 1,000-unit quantities.
