Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All AC timings for the Asynch GTL+ signals are referenced to the BCLK0 rising edge at Crossing Voltage. All
Asynch GTL+ signal timings are referenced at GTLREF. PWRGOOD is referenced to the BCLK0 rising edge
at 0.5 * VCC.
3. These signals may be driven asynchronously.
4. Refer to the PWRGOOD definition for more details regarding the behavior of this signal.
5. Length of assertion for PROCHOT# does not equal internal clock modulation time. Time is allocated after the
assertion and before the deassertion of PROCHOT# for the processor to complete current instruction
execution.
6. See Section 7.2 for additional timing requirements for entering and leaving the low power states.
NOTES:
1. Before the deassertion of RESET#.
2. After clock that deasserts RESET#.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. Not 100% tested. Specified by design characterization.
3. All AC timings for the TAP signals are referenced to the TCK signal at 0.5*VCC at the processor pins. All TAP
signal timings (TMS, TDI, etc) are referenced at 0.5*VCC at the processor pins.
4. Rise and fall times are measured from the 20% to 80% points of the signal swing.
5. Referenced to the rising edge of TCK.
6. Referenced to the falling edge of TCK.
7. Specifications for a minimum swing defined between TAP VT- to VT+. This assumes a minimum edge rate of
0.5 V/ns.
8. TRST# must be held asserted for 2 TCK periods to be guaranteed that it is recognized by the processor.
9. It is recommended that TMS be asserted while TRST# is being deasserted.
