Unit Note or Test Condition
mA Assuming operating state S0,
that means active. Note that
since the device is mostly in an
internal sleep state in a “typical”
application, the typical average
current consumption is far less
than the maximum value. It is
assumed that in a normal
environment, the device is in an
internal sleep state for
approximately 90% of the
operating time of the platform.
mA Pins LRESET#, LFRAME#,
LADn,SERIRQ = V_DD.
Assuming operating state S0 with
active clock. No ongoing internal
TPM operation. The device is in
an internal sleep state.
µA Pins LRESET#, LFRAME#,
LADn,SERIRQ = V_DD and LCLK =
GND.
Assuming operating state S3 with
clock stopped.
Obviously, this value is zero if the
TPM is not powered in S3 state
(this is platform dependent).
Note: Current consumption does not include any currents flowing through resistive loads on output pins! For
the definition of power/operating states, please refer to the ACPI standard.
Note: Device sleep mode will be entered after 30 seconds of inactivity after the last TPM command was
executed.
