Notes to
(1) Typical values are for T
A
= 25 °C, V
CCINT
= 3.3 or 2.5 V, and V
CCIO
= 1.5 V, 1.8 V, 2.5 V, or 3.3 V.
(2) This value is specified for normal device operation. The value may vary during power-up. This applies for all V
CCIO
settings (3.3, 2.5,
1.8, and 1.5 V).
(3) V
I
= ground, no load, no toggling inputs.
(4) This value applies to commercial and industrial range devices. For extended temperature range devices, the V
SCHMITT
typical value is
300 mV for V
CCIO
= 3.3 V and 120 mV for V
CCIO
= 2.5 V.
(5) The
TCK
input is susceptible to high pulse glitches when the input signal fall time is greater than 200 ns for all I/O standards.
(6) This is a peak current value with a maximum duration of t
CONFIG
time.
(7) Pin pull-up resistance values will lower if an external source drives the pin higher than V
CCIO
.
