DC and Power Characteristics
VCC
VCC = 1.575 V
VCC = 1.425 V
Activation trip point:
Va = 0.85 V ± 0.25 V
Deactivation trip point:
Vd = 0.75 V ± 0.25 V
VCC = VCCI + VT
Where VT can be from 0.58 V to 0.9 V (typically 0.75 V)
Region 1: I/O Buffers are OFF
Region 4: I/O
buffers are ON.
I/Os are functional
(except differential inputs)
but slower because VCCI is
below specification. For the
same reason, input buffers do not
meet VIH / VIL levels, and output
buffers do not meet VOH / VOL levels.
Region 5: I/O buffers are ON
and power supplies are within
specification.
I/Os meet the entire datasheet
and timer specifications for
speed, VIH / VIL, VOH VOL, etc.
Region 2: I/O buffers are ON.
I/Os are functional (except differential inputs)
but slower because VCCI / VCC are below
specification. For the same reason, input
buffers do not meet VIH / VIL levels, and
output buffers do not meet VOH / VOL levels.
Region 3: I/O buffers are ON.
I/Os are functional; I/O DC
specifications are met,
but I/Os are slower because
the VCC is below specification
Region 1: I/O buffers are OFF
Activation trip point:
Va = 0.9 V ±0.3 V
Deactivation trip point:
Vd = 0.8 V ± 0.3 V
Min VCCI datasheet specification
voltage at a selected I/O
standard; i.e., 1.425 V or 1.7 V
or 2.3 V or 3.0 V
