Notes to
(1) Typical values are for T
A
= 25°C, V
CCINT
= 1.8 V and V
CCIO
= 1.2, 1.5, 1.8, 2.5, or 3.3 V.
(2) This value is specified for normal device operation. The value may vary during power-up. This applies to all V
CCIO
settings (3.3, 2.5, 1.8, 1.5,
and 1.2 V).
(3) V
I
= ground, no load, and no toggling inputs.
(4) Commercial temperature ranges from 0°C to 85°C with the maximum current at 85°C.
(5) Not applicable to the T144 package of the 5M240Z device.
(6) Only applicable to the T144 package of the 5M240Z device.
(7) Industrial temperature ranges from –40°C to 100°C with the maximum current at 100°C.
(8) 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.
(9) 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.
(10) This is a peak current value with a maximum duration of t
CONFIG
time.
(11) Pin pull-up resistance values will lower if an external source drives the pin higher than V
CCIO
.
