Electrical Specifications
Notes:
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
All AC timings for the Asynchronous GTL signals are referenced to the BCLK_P rising edge at Crossing 
Voltage (V
CROSS
). VCCPWRGOOD, VTTPWRGOOD and VDDPWRGOOD are referenced to BCLK_P rising edge 
at 0.5 * V
TT
.
3.
These signals may be driven asynchronously.
4.
Refer to 
 for additional timing requirements for entering and leaving low power states.
5.
xxPWRGOOD signal has no edge rate requirement, but edge must be monotonic.
6.
VDDPWRGOOD must be asserted no later then VCCPWRGOOD. There is no releationship between 
VDDPWRGOOD and VCC ramp.
7.
There is no dependency between VDDPWRGOOD and VTTPWRGOOD assertion.
8.
VTTPWRGOOD must accurately reflect the state of VTT and must not glitch whenever VTT or VDD is 
applied.
9.
VTT must read VTTFINAL before VCCPWRGOOD assertion.
10. It may be required to add delay on the board to meet the 1 ms minimum processor requirement.
11. Based on a test load of 50 Ω to V
TT
.
12. Specified for synchronous signals.
13. Applies to PROCHOT# signal only. Please se
 for information regarding 
Power-On Configuration options.
14. Rise time is measured from 10% to 90% of the final voltage.
Notes:  
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
Not 100% tested. Specified by design characterization.
3.
It is recommended that TMS be asserted while TRST# is being deasserted.
Notes:
1.
Platform support for VID transitions is required for the processor to operate within specifications.
