Electrical Specifications
This section contains preliminary information on new products in production. The specifications
are subject to change without notice.
4.1
Absolute Maximum Ratings
Warning:
The following values are stress ratings only. Functional operation at the maximum ratings is not
implied nor guaranteed. Functional operating conditions are given in the AC and DC specification
tables. Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent
damage.
Extended exposure to the maximum ratings may affect device reliability. Furthermore, although the
Pentium processor with MMX technology contains protective circuitry to resist damage from
Electrostatic Discharge (ESD), always take precautions to avoid high static voltages or electric
fields.
4.2
DC Specifications
Tables 19, 20, 21 and 22 list the DC specifications which apply to the low-power embedded
Pentium processor with MMX technology.
4.2.1
Power Sequencing
There is no specific sequence required for powering up or powering down the V
CC2
and V
CC3
power supplies. However, it is recommended that the V
CC2
and V
CC3
power supplies be either both
ON or both OFF within one second of each other.
The I/O voltage V
CC3
is 2.5 V. The core voltage V
CC2
is 1.9 V for PPGA. The core voltage V
CC2
for the HL-PBGA package type is 1.8 V (166 MHz) or 2.0 V (266 MHz).
