ISL9206A FlexiHash+ For Battery Authentication

DATASHEET ISL9206A FlexiHash+™ For Battery Authentication The ISL9206A is a highly cost-effective fixed-secret hash engine based on Intersil’s second generation FlexiHash™ technology. The device authentication is achieved through a challenge-response scheme customized for low-cost applications, where cloning via eavesdropping without knowledge of the devic.

Features

• Challenge-response based authentication scheme using 32-Bit challenge code and 8-Bit authentication code.
• Fast and flexible authentication process. Multi-pass authentication can be used to achieve the highest security level if necessary.
• 16x8 OTP ROM stores up to three sets of 32-Bit host-selectable secrets with additional programmable memory for storage of up to 48-Bits of ID code and/or pack information.
• FlexiHash+™ engine uses two sets of 32-Bit secrets for authentication code generation.
• Non-unique mapping of the secret key to an 8-Bit authentication code maximizes hacking diffic.
