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 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.

? 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 exhaustive key search (superior to SHA-1).

? 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 communicates with all

8250-compatible 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

after a bus inactivity time-out period

? 5 Ld SOT-23 or 8 Ld TDFN (2mm x 3mm) packages

? -20°C to +85°C operating temperature range

? Pb-free plus anneal available (RoHS compliant)

Applications

? Battery Pack Authentication

? Printer Cartridges

? Add-on Accessories

? Other Non-Monetary Authentication Applications
