Electrical Specifications
64 Datasheet
Notes:
1. Unless otherwise noted, all specifications in this table apply to all processors. These specifications are based on pre-silicon
characterization.
2. Individual processor VID values may be calibrated during manufacturing such that two devices at the same speed may have
different settings.
3. These voltages are targets only. A variable voltage source should exist on systems in the event that a different voltage is
required.
4. The VCC voltage specification requirements are measured across the remote sense pin pairs (VCC_SENSE and
VSS_VCC_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20 MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1 M
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
5. The VTTA, and VTTD voltage specification requirements are measured across the remote sense pin pairs (VTTD_SENSE and
VSS_VTTD_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1 M
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
6. The VSA voltage specification requirements are measured across the remote sense pin pairs (VSA_SENSE and
VSS_VSA_SENSE) on the processor package. Voltage measurement should be taken with a DC to 100 MHz bandwidth
oscilloscope limit (or DC to 20 MHz for older model oscilloscopes), using a 1.5 pF maximum probe capacitance, and 1 M
minimum impedance. The maximum length of the ground wire on the probe should be less than 5 mm to ensure external
noise from the system is not coupled in the scope probe.
7. The processor should not be subjected to any static VCC level that exceeds the VCC_MAX associated with any particular current.
Failure to adhere to this specification can shorten processor lifetime.
8. Minimum VCC and maximum ICC are specified at the maximum processor case temperature (TCASE). ICC_MAX is specified at the
relative VCC_MAX point on the VCC load line. The processor is capable of drawing ICC_MAX for up to 5 seconds.
9. The processor should not be subjected to any static VTTA, VTTD level that exceeds the VTT_MAX associated with any particular
current. Failure to adhere to this specification can shorten processor lifetime.
10. This specification represents the VCC reduction or VCC increase due to each VID transition, see Section 7.1.8.3.
11. Baseboard bandwidth is limited to 20 MHz.
12. N/A
13. DC + AC + Ripple = Total Tolerance
14. For Power State Functions see Section 7.1.8.3.5.
15. VSA_VID does not have a loadline, the output voltage is expected to be the VID value.
16. VCCD tolerance at processor pins. Tolerance for VR at remote sense is ±3.3%*VCCD.
17. The VCCPLL, VCCD01, VCCD23 voltage specification requirements are measured across vias on the platform. Choose VCCPLL,
VCCD01, or VCCD23 vias close to the socket and measure with a DC to 100MHz bandwidth oscilloscope limit (or DC to 20 MHz
for older model oscilloscopes), using 1.5 pF maximum probe capacitance, and 1M minimum impedance. The maximum
length of the ground wire on the probe should be less than 5 mm to ensure external noise from the system is not coupled in
the scope probe.
18. VCC has a Vboot setting of 0.0V and is not included in the PWRGOOD indication.
19. VSA has a Vboot setting of 0.9V.
