CMOS Signals
CMOS input signals are shown in
Table 5
. Legacy output FERR#, IERR# and other non-
AGTL+ signals (THERMTRIP# and PROCHOT#) utilize Open Drain output buffers. These
signals do not have setup or hold time specifications in relation to BCLK[1:0]. However,
all of the CMOS signals are required to be asserted for at least three BCLKs in order for
the processor to recognize them. See
Section 3.11
for the DC for the CMOS signal
groups.
3.10
Maximum Ratings
Table 6
lists the processor’s maximum environmental stress ratings. The processor
should not receive a clock while subjected to these conditions. Extended exposure to
the maximum ratings may affect device reliability. Furthermore, although the processor
contains protective circuitry to resist damage from Electro-Static Discharge (ESD), one
should always take precautions to avoid high static voltages of electric fields.

Processor DC Specifications
Note:
The processor DC specifications in this section are defined at the processor core (pads)
unless noted otherwise.
See
Table 5
for the pin signal definitions and signal pin assignments. Most of the signals
on the FSB are in the AGTL+ signal group. The DC specifications for these signals are
listed in
Table 8
. DC specifications for the CMOS group are listed in
Table 9
.
Table 7
through
Table 10
list the DC specifications for the Intel

Processor
1.66 GHz/1.83 GHz and are valid only while meeting specifications for junction
temperature, clock frequency, and input voltages. The Highest Frequency Mode (HFM)
and Lowest Frequency Mode (LFM) refer to the highest and lowest core operating
frequencies supported on a particular processor. Active mode load line specifications
apply in all states. V
CC,BOOT
is the default voltage driven by the voltage regulator at
power up in order to set the VID values. Unless specified otherwise, all specifications
for the Intel
®
Celeron
®
Processor 1.66 GHz/1.83 GHz are at Tjunction = 100
°
C. Care
should be taken to read all notes associated with each parameter.
The Intel
®
Celeron
®
Processor 1.66 GHz/1.83 GHz does not support Enhanced Intel
SpeedStep
®
Technology (EIST), therefore HFM and LFM transitions are not supported.

Notes:
1.
For functional operation, all processor electrical, signal quality, mechanical and thermal specifications
must be satisfied.
2.
Excessive overshoot or undershoot on any signal will likely result in permanent damage to the
processor.
3.
Storage temperature is applicable to storage conditions only. In this scenario, the processor must not
receive a clock, and no pins can be connected to a voltage bias. Storage within these limits will not
affect the long term reliability of the device. For functional operation, please refer to the processor
case temperature specifications.
