ISL6296A
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 necessary
- 16x8 OTP ROM stores up to three sets of 32-bit host selectable secrets with additional programmable memory for storage of up to 48 bits of ID code and/or pack information
- Flexi Hash 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 exhaustive key search (superior to SHA-1)
- Supports 1-cell Li-ion/Li-Poly and 3-cell series Ni MH 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 and transfer bit-rate up to 23kbps
- True “Zero Power” sleep mode
- automatically entered...
