DATASHEET
Chapter 5 Pin Descriptions
This chapter is organized by a set of pin configurations (organized by package type) followed by a
corresponding pin list organized alphabetically. A comprehensive and detailed description list of each
signal (named in the pin list) is organized by function in Table 5.2, “USB251x Pin Descriptions,” on
page 22. Please refer to Table 5.3, “Buffer Type Descriptions,” on page 27 for a list of buffer types.
The “N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal
is at a low voltage level. When “N” is not present after the signal name, the signal is asserted when it
is at the high voltage level. The terms assertion and negation are used exclusively. This is done to
avoid confusion when working with a mixture of “active low” and “active high” signals. The term assert,
or assertion, indicates that a signal is active, independent of whether that level is represented by a
high or low voltage. The term negate, or negation, indicates that a signal is inactive.
