SYMBOL
1. One output at a time for a maximum of one second. V
OUT
= 0.5V was selected to avoid test problems by
tester ground degradation. Characterized, but not 100% tested.
2. Typical values are at V
CC
= 3.3V and T
A
= 25°C.
3. I
CC
/ MHz = (0.0025 x I/O cell fanout) + 0.042.
e.g. An input driving four I/O cells at 40MHz results in a dynamic I
CC
of approximately ((0.0025 x 4) + 0.042) x 40 = 2.08mA.
4. For a typical application with 50% of I/O pins used as inputs, 50% used as outputs or bi-directionals.
5. This parameter limits the total current sinking of I/O pins surrounding the nearest GND pin.

1. All timings measured with one output switching, fast output slew rate setting, except tsl.
2. The delay parameters are measured with Vcc as I/O voltage reference. An additional 0.5ns delay is incurred when Vccio is
used as I/O voltage reference.

ispGDX240VA Maximum ∆ GRP Delay vs. I/O Cell Fanout
ispGDX240VA timings are specified with a GRP load
(fanout) of four I/O cells. The figure below shows the ∆
GRP Delay with increased GRP loads. These deltas
apply to any signal path traversing the GRP (MUXA-D,
OE, CLK/CLKEN, MUXsel0-1). Global Clock signals
which do not use the GRP have no fanout delay adder.
