ISL6296 Key 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
- 16x8 OTP ROM stores up to three sets of 32-Bit hostselectable secrets with additional programmable memory for storage of
- FlexiHash engine uses two sets of 32-Bit secrets for authentication code generation
- Non-unique mapping of the secret key to an 8-Bit authentication code maximizes hacking difficulty due to need for exhaus
- 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 and 8 Ld TDFN (2mm x 3mm) packages
ISL6296 Applications
- a light-weight subset of Intersil’s ISD bus interface. The XSD bus is patible for use with serial ports offered by all 8250 patible UART’s or a single GPIO (gen
