ISL9206
FlexiHash+ For Battery Authentication
The ISL9206 is a highly cost-effective fixed-secret hash
engine based on Intersil’s second generation FlexiHash
technology. The device authentication is achieved through a
challenge-response scheme customized for low-cost
applications, where cloning via eavesdropping without
knowledge of the device’s secret code is not economically
viable. When used for its intended applications, the ISL9206
offers the same level of effectiveness as other significantly
more expensive high-maintenance hash algorithm and
authentication schemes.
The ISL9206 has a wide operating voltage range, and is
suitable for direct powering from a 1-cell Li-Ion/Li-Poly or a
3-cell series NiMH battery pack. The ISL9206 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 cell
terminals of a battery pack, and includes on-chip voltage
regulation circuit, POR, and a non-crystal based oscillator for
bus timing reference.
Communication with the host is achieved through a single-
wire XSD interface - a light-weight subset of Intersil’s ISD bus
interface. The XSD bus is compatible for use with serial ports
offered by all 8250 compatible UART’s or a single GPIO
(general purpose input and output) pin of a microprocessor.
A clone prevention solution utilizing the ISL9206 offers
safety and revenue protection at the lowest cost and power,
and is suitable for protection against after-market
replacement for a wide variety of low-cost applications.
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

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
