DATASHEET To request the full datasheet, please visit .intersil./products/isl6296a FlexiHash™ For Battery Authentication ISL6296A The ISL6296A is a highly cost-effective fixed-secret hash engine based on Intersil’s FlexiHash™ technology. The device’s authentication is achieved through a challenge response scheme, which is customized for low-cost applications where cloning via eavesdropping without knowledge of the...
ISL6296A Key Features
- Challenge-response based authentication scheme using 32-bit challenge code and 8-bit authentication code
- Fast and flexible authentication process. Multipass authentication can be used to achieve the highest security level if
- 16x8 OTP ROM stores up to three sets of 32-bit host selectable secrets with additional programmable memory for storage o
- FlexiHash engine uses two sets of 32-bit secrets for authentication code generation
- Nonunique mapping of the secret key to an 8-bit authentication code maximizes hacking difficulty due to need for exhaust
- Supports 1-cell Li-ion/Li-Poly and 3-cell series NiMH battery packs (2.6V ~ 4.8V operation), or powered by the XSD bus
- XSD single-wire host bus interface municates with all 8250-patible UART’s or a single GPIO. Supports CRC on read data an
- True “Zero Power” sleep mode
- automatically entered after a bus inactivity time-out period
- 5 Ld SOT-23, 8 Ld TDFN and 8 Ld µTQFN packages
