• Manufacturer Part Number: upd720110a
• Description: Usb 2.0 Hub Controller
• Manufacturer: Renesas Electronics Corporation.

Hub Event Timings (Continued)
Inter-packet delay for full-speed
Inter-packet delay for device response with
detachable cable for full-speed
SetAddress() completion time
Time to complete standard request with no
data
Time to deliver first and subsequent
(except last) data for standard request
Time to deliver last data for standard
request
Time for which a suspended hub will see a
continuous SE0 on upstream before
beginning the high-speed detection
handshake
Time a hub operating in non-suspended
full-speed will wait after start of SE0 on
upstream before beginning the high-speed
detection handshake
Time a hub operating in high-speed will
wait after start of SE0 on upstream before
reverting to full-speed
Time a hub will wait after reverting to full-
speed before sampling the bus state on
upstream and beginning the high-speed
will wait after start of SE0 on upstream
before reverting to full-speed
Minimum duration of a Chirp K on
upstream from a hub within the reset
protocol
Time after start of SE0 on upstream by
which a hub will complete its Chirp K within
the reset protocol
Time between detection of downstream
chip and entering high-speed state
Time after end of upstream Chirp at which
hub reverts to full-speed default state if no
downstream Chirp is detected
