Updated bulleted lists. USB signal drive strength,
USB differential pair pin location and downstream
port power control / over-current detection items
moved from first (strap-configurable) bulleted list to
the second (EEPROM-configurable) bulleted list.
Added enabling of battery charging to the first
bulleted list.
Clarified introductory sentence.
Updated VBUS_DET buffer type to “I” and changed
description to: “For self-powered applications with a
permanently attached host, this pin must be
connected to a dedicated host control output, or
connected to the 3.3 V domain that powers the
host (typically VDD33).”
Updated CRFILT and PLLFILT pin descriptions.
Removed redundant sentence: “External Clock:
50% duty cycle 10%, 24/48 MHz 350 ppm, jitter
< 100 ps rms”. This information is provided in
Section 7.2, "External Clock," on page 45.
Removed ceramic resonator information.
Replaced “1.8 V CMOS Logic” with “1.2 V CMOS
Logic”. Updated XTALOUT description.
Updated CRFILT and PLLFILT pin descriptions.
Removed the 49-BGA option.
Changed ordering codes for non-industrial
USB2513B and USB2514B. Last character was
changed from “G” to “C”.
Removed support for ceramic resonator.
Added Max Power Supported = (TJ, max.spec. - Tamb)/ ΘJA
General refresh, corrected grammatical errors and
unified tone.
