Note:
1. I
TT
listed in this table is the sum of I
TTA
and I
TTD
.
2. This table is intended to aid in reading discrete points on Figure 2-10.
3. The V
TT_MIN
and V
TT_MAX
loadlines represent static and transient limits. Each is characterized by a 31.5 mV
offset from V
TT_TYP
.
4. The loadlines specify voltage limits at the die measured at the VTTD_SENSE and VSS_SENSE_VTTD lands.
Voltage regulation feedback for regulator circuits must also be taken from VTTD_SENSE and
VSS_SENSE_VTTD lands.
Notes:
1. The V
TT_MIN
and V
TT_MAX
loadlines represent static and transient limits. Each is characterized by a 31.5 mV
offset from V

.
2. Refer to Table 2-4 for processor VTT_VID information.
