Processor in the 478-Pin Package
2.10.1 Flexible Motherboard Guidelines (FMB)
The FMB guidelines are estimates of the maximum values the Celeron processor in the 478-pin
package will have over certain time periods. The values are only estimates and actual specifications
for future processors may differ. The Celeron
processor in the 478-pin package may or may not
have specifications equal to the FMB value in the foreseeable future. System designers should meet
the FMB values to ensure their systems will be compatible with future releases of the Celeron
processor in the 478-pin package.
NOTES:
1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical
data. These specifications will be updated with characterized data from silicon measurements at a later date.
2. These voltages are targets only. A variable voltage source should exist on systems in the event that a
different voltage is required. See Section 2.4 and Table 2 for more information.
3. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE pins at the
socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe capacitance, and 1 M
Ω minimum
impedance. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external
noise from the system is not coupled into the scope probe.
4. Refer to Table 7 and Figure 3 for the minimum, typical, and maximum V
CC allowed for a given current. The
processor should not be subjected to any V
CC and I
CC
combination wherein VCC exceeds V
CC_MAX
for a
given current. Moreover, V
CC should never exceed the VID voltage. Failure to adhere to this specification can
shorten the processor lifetime.
5. V
CC_MIN
is defined at I
CC_MAX
.
6. The current specified is also for AutoHALT State.
7. The maximum instantaneous current the processor will draw while the thermal control circuit is active as
indicated by the assertion of PROCHOT# is the same as the maximum I
CC
for the processor.
8. I
CC
Stop-Grant and I
CC
Sleep are specified at V
CC_MAX.
9. These specifications apply to processors with a VID setting of 1.75 V.
