ISL9206A

• Product introduction

ISL9206A

Key features

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

description

The ISL9206A is a cost-effective, secured-secret hashing engine based on Intersil's second-generation FlexiHash™ technology. Device authentication is a challenge that is economically unviable through a customized, low-cost application, cloning secret code by eavesdropping on the device's secret code without knowledge - response scenarios. When used for its intended application, ISL9206A provides the same level of effectiveness as other significantly more expensive high-maintenance hashing algorithms and authentication schemes.

The ISL9206A has a wide operating voltage range and is suitable for direct power from 1-cell Li-ion/Li-Poly or 3-cell series NiMH battery packs. 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 battery terminals of a battery pack, including on-chip voltage regulation circuitry, 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 8250 compatible UART or microprocessor serial ports with a single GPIO (General Purpose Input and Output) pin.

The anti-cloning solution that utilizes the ISL9206A provides security and revenue protection with minimal cost and power consumption, and is suitable for protecting various alternatives to low-cost applications in the aftermarket.
