1. Overview

Overview
The S2R72A44F12C4, S2R72A43F12C4, S2R72A42F12C4, S2R72A44F07E2, S2R72A43F07E2 and
S2R72A42F07E2 are USB hub controller LSIs supporting USB 2.0 (Universal Serial Bus Specification Revision
2.0) high-speed mode. They meet the stringent quality requirements for automotive use and are capable of
operating at temperatures up to 105°C.
All LSIs in the range feature two downstream ports supporting high-speed mode, while the number of
downstream ports supporting full-speed mode varies for individual LSI types.
Using the A44, A43 or A42 enables the main chip USB host port to be easily expanded to allow the connection of
multiple USB devices such as mobile audio players or ETC devices to car navigation systems.

VBUS switch management
Dx{x=1-4}_VBUSEN pins corresponding to each down ports are surved for this purpose.
VBUS switch devices connected to those pins can be managed individually (Individual mode, i.e. MODE2 =
High) or concurrently (Gang mode, i.e. MODE2 = Low).
Assertion of VBUSEN signals are caused only by SetPortFeature(PORT_POWER) standard request which is
issued by the Host. Further conditions as listed below are required for VBUSEN signals to be asserted at that
moment.
- MODE1 pin is set to High (i.e. bPwrOn2PwrGood = 0b1)
- The LSI is under configured condition (as USB standard meaning) as a result of receiving SetConfiguration()
standard request from the Host.
- Dx{x=1-4}_VBUSFLG pins correspoinding to each of down ports are not forced to low.
If each of those VBUSFLG signals is asserted, PORT_OVER_CURRENT status on each down port is set.
Those statuses can be checked with GetPortStatus() standard request which is issued repeatedly by ordinaly host
stacks.
Lack of at least one of above conditions causes nagation of VBUSEN signal. Once VBUSEN is negated, it is not
asserted again without reception of SetPortFeature(PORT_POWER) even if conditions are returned in order.
In Gang mode, D1_VBUSEN alone is served for the VBUS management function.
Please refer to the USB 2.0 standard for USB defined things such as bPwrOn2PwrGood condition, standard
requests, Individual mode or Gang mode.

*1:
TYP values are mean current for actual operation at recommended operating conditions (Ta = 25°C). MAX
values are estimated from TYP values. Those values are correlative to “bus domination” ratio because the
S2R72A44/A43/A42F12C4 LSI saves power consumption in the idle state.

*2:
TYP values are peak current for actual operation at recommended operating conditions (Ta = 25°C). MAX
values are estimated from TYP values.
*3:
Current consumption from HVDD power supply is influenced by cable length when transmittiong on FS
