1 FlexiHash™ For Battery Authentication The ISL6296 is a highly cost-effective fixed-secret hash engine based on Intersil’s FlexiHash™ technology.
The device authentication is achieved through a challengeresponse scheme customized for low-cost applications, where cloning via eavesdropping without knowledge of the device’s secret code is not economically viable.
When used for its intended applications, the ISL6296 offers the same level of effectiveness as other significantly more expensive high maintenance monetary-grade hash algorithm and authentication schemes.
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.
The ISL6296 can also be powered by the XSD bus when the bus pull-up voltage is 3.
3V or higher.
The device connects directly to the cell terminals of a battery pack, and includes on-chip voltage regulation circuit, POR, and a non-crystal based oscillator for bus timing reference.
Communication with the host is achieved through a singlewire XSD interface - a light-weight subset of Intersil’s ISD bus interface.
The XSD bus is compatible for use with serial ports offered by all 8250 compatible UART’s or a single GPIO (general purpose input and output) pin of a microprocessor.
A clone prevention solution utilizing the ISL6296 offers safety and revenue protection at the lowest cost and power, and is suitable for protection against after-market replacement for a wide variety of low-cost applications.
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 hostselectable secrets with addi...
