Use Conditions
The Use Conditions define run-time parameters such as the operating mode (eg. 24/7), activity factor, max frequency, temperature range etc. for the application being
used.
Certain Use Conditions may have an effect on the lifetime of the product.
Please consult Avnet Integrated / MSC Technical Support if there are questions concerning specific Use Conditions when using the selected MSC module for the
target application.
Signal description
Pins are listed in the following tables with the power rail associated with that pin, and for input and I/O pins, with the input voltage tolerance. The pin
power rail and the pin input voltage tolerance
may
be different.
An additional label, “Sus”, indicates that the pin is active during suspend states (S3, S4, S5). If suspend modes are used, then care must be taken to
avoid loading signals that are active during suspend to avoid excessive suspend mode current draw.
I = Input.
O = Output.
OD = Open Drain output.
I/OD = Bi-directional Input/Open Drain Output Pin.
I/O = Bi-directional Input/Output.
ePU = external pull-up resistor on COM Express module.
ePD = external pull-down resistor on COM Express module.
eSR = external series resistor on COM Express module.
iPU = integrated pull-up resistor inside PCH or other IC, real value may vary from nominal one.
iPD = integrated pull-down resistor inside PCH or other IC, real value may vary from nominal one.
