Not an expert legal, but I believe "useful lifetime" is for accounting
purposes, its not a statement on how long a device is expected to remain in
working order, its used to define when its value depreciates as an asset.
Cars, fax machines, computers etc all appear to have the standard 5 years

From data sheet:

SLB 9670 TCG Family 2 Level 00 Rev. 01.16 Data Sheet, Revision 1.0,
1.1 Power Management
In the SLB 9670, power management is handled internally; no explicit
power-down or standby mode is
available. The device automatically enters a low-power state after each
transaction. If a transaction is started on the SPI bus from the host
platform, the device will wake immediately
and will return to the low-power mode after the transaction has been
4.2 Functional Operating Range
1) *The useful lifetime of the device is 5 (five) years with a duty cycle
(that means, a power-on time) of 100%. A useful*
*lifetime of 7 (seven) years can be guaranteed for a duty cycle of 70%.
For both scenarios, it is assumed that the device*
*will be used for calculations for approximately 5% of the maximum useful
Is it true? This is disqualification. Industrial equipment should work
much longer, 15-20 years. It's not suitable for industrial equipment.
It's good for ink toner cartridge.
