                 Intersil Announces the Industry’s Most Cost-Effective,
           Fixed Secret Hash Engine, Authentication IC for Cell Phone Makers
                             --ISL6296 prevents use of counterfeit battery packs
                    --Single-chip solution with Intersil’s unique Flexihash™ technology
--Provides same level of effectiveness as other significantly more expensive and higher maintenance solutions

MILPITAS, CA, February 3, 2005 – Intersil Corporation (NASDAQ: ISIL), a world leader in the design
and manufacture of high performance analog solutions, announced today 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 add-on 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.

―Intersil has developed this innovative solution in response to the many requests from cellular handset
OEMs to protect against the use of counterfeit battery packs in their products,‖ said Arman Naghavi,
director of Handheld Products at Intersil. ―In recent months there have been a number of incidents, which
have caused serious harm to users of cell phones with counterfeit battery packs. These incidents have been
publicized in the world press and potentially damage the reputation and market perception of these cell
phone handset OEMs. The ISL6296 prevents the use of fake battery packs and offers OEMs a very cost-
effective solution for authentication with a very high level of security.‖

When used with Intersil’s battery authentication firmware, the ISL6296 solution offers a simple yet
powerful means of verifying the authenticity of a cell phone battery pack. Device authentication is
achieved through a challenge-response authentication scheme customized 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 1-cell Li-
Ion/Li-Poly or a 3-cell series NiMH battery pack. This solution is ideal for battery pack and accessories
authentication, including battery charging systems and add-on products. Other potential markets are IP
protection of reference designs and authentication of disposable items such as printer cartridges.

The ISL6296 combines an on-chip fixed 32+32-bit secret code with Intersil’s Flexihash programmable
hashing algorithm to provide a very secure challenge response authentication scheme. The device uses 1or
3 selectable 32-bit secrets adding an additional level of security. The secrets are programmable by the
manufacturer and are read-inhibited by using a single lockout fuse bit. The device uses Intersil’s XSD
bus, which is a simple single wire serial data bus for communicating with a host system at up to 23Kbps.
The XSD bus is a subset of the Intersil ISD bus protocol that can be used with any 16550 compatible
UART. The host sending a 32-bit challenge word and receiving an 8-bit response initiate the authentication
process. Innovative software schemes may also be implemented to add additional levels of security. Please
contact Intersil for details.

The ISL6296 is available now in a 5-pin SOT-23 package in standard lead finish or Pb-free. The suggested
unit price for 1,000 piece quantities is $1.05. Additional information on these and other high performance
power solutions can be obtained online from Intersil’s web site at:
