Signal Type Definitions
Signal Descriptions
The signals of 82563EB/82564EB are defined as follows:
Signals may be further qualified to indicate whether an internal pull-up or pull-down is normally
active. Unless otherwise stated, internal pull-up and pull-down impedances are between 50 K
and 130 K
rely on a device’s internal pull-up or pull-down signal to be active. Care should be taken to ensure
there are no long traces, such as far-away test points or errant trace routings, on any inputs which
rely solely on internal pull-devices. Excess capacitance of dangling traces may generate charge
and/or noise on inputs which exceeds the capability of the internal pull-device, leading to
unpredictable component behavior.
In addition to a primary type, each pin can be classified according to one of the following sub-types
based on its electrical characteristics, such as input and output voltages and drive strengths.
