1) NU (Not Used) on STR910FAW devices. D10 is not connected, C11 must be pulled up by a 1.5 kOhm resistor to VDDQ.
2) No USBCLK function on STR910FAW devices.
3) No PHYCLK function on STR910FAW devices.
STR91x LFBGA144 Ball Connections
PLLVSSQ
In
devices and should NOT be connected to ground or any other signal. There are total of 9
NC (no connection) balls.
Balls H1 and G4 are assigned as EMI bus write signals (EMI_BWR_WRLn and
EMI_WRHn). These two balls can also be configured by the user as EMI low or high byte
select signals (EMI_LBn and EMI_UBn).
The PLLGND (B8) and PLLVDDQ (C9) balls can be connected to VSSQ and VDDQ.
