Unless otherwise noted, all parameters are established over the operational supply voltage and temperature
range of the device as follows: T
limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested. (Continued)

Pulse width narrower than the de-glitch time will not
cause the device to wake up
From falling-edge of break command issued by host to
falling-edge of break command returned by device
From when the ‘11’ Opcode is detected to the shut-off
of the internal regulator
From the last transition detected on the XSD bus to the
device going into sleep mode
From the last BT of the 2nd write data frame to when
device is ready to accept the next instruction
From the last BT of the Challenge Code Word from the
host to the Authentication Code being available for
read
From the last BT of the Soft-Reset instruction issued
by the host to the falling-edge of break command
returned by device
System ground.
No connection.
Supply voltage.
Production test I/O pin. Used only during production testing. Must be left floating during
normal operation.
Communication bus with weak internal pull-down to VSS. This pin is a Schmitt-trigger input
and an open-drain output. An appropriate pull-up resistor is required on the host side.
