ISL9206A

• Product Introduction

ISL9206A

Key features:

• Challenge-based authentication program that utilizes 32-digit challenge codes and 8-digit verification codes.
• Fast and flexible identity verification process. Multi-pass authentication, which can be used to achieve the highest level of security, if necessary.
• The 16x8 OTP ROM stores up to three sets of 32-bit hosts with optional secret additional programmable memory for storing up to 48-bit ID codes and/or packet information.
• The FlexiHash+ ™ engine uses two sets of CAPTCHAs to generate 32-bit secrets.
• Non-unique keys mapped to 8-digit CAPTCHAs maximize the difficulty of hacking and require exhaustive key searches (better than SHA-1).
• A 3-cell series nickel-metal hydride (NiMH) battery pack that supports 1-cell Li-ion/Li-Poly (2.6V to 4.8V operation) or is powered by an XSD bus.
• The XSD single-wire host bus interface is compatible with all 8250-UARTs or single GPIOs. CRC reads data with a transmission rate of up to 23kbps.
• True "zero-power" sleep mode (automatically enters after a timeout when the bus is idle)
• 5 LD SOT-23 or 8 LD TDFN Package (2mmx3mm)
• Operating temperature range of -20°C to +85°C
• Lead-free (RoHS compliant)

description

ISL9206A is a cost-effective fixed confidential hash engine based on Intersil's second-generation FlexiHash™ technology. Device authentication is a customized, low-cost application that clones through eavesdropping on the device's secret code without knowledge of the economically unfeasible challenge – response scenarios. When used in its intended application, ISL9206A provide the same level of effectiveness as other, significantly more expensive high-maintenance hashing algorithms and authentication schemes.

ISL9206A has a wide operating voltage range and is suitable for direct power from 1-cell Li-ion/Li-Poly or 3-node series NiMH battery packs. 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 battery terminals of a battery pack and includes an on-chip voltage regulation circuit, POR, and an amorphous oscillator for bus timing reference.

Communication with the host is via a single-wire XSD interface (a lightweight subset of Intersil's ISD bus interface). The XSD bus is compatible using all of the 8250 provided serial ports with a single GPIO (Universal Input Output) pin for UART or microprocessors.

Anti-clone solutions, leveraging ISL9206A provide security and revenue protection, minimal cost and power consumption, and are suitable for protecting a variety of alternatives to low-cost applications in the aftermarket.
