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 device’s secret code is not economically
viable. When used for its intended applications, the
ISL9206A offers the same level of effectiveness as other
significantly more expensive high-maintenance hash
algorithm and authentication schemes.
The ISL9206A 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 ISL9206A 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 single
wire 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 ISL9206A 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.
