Datasheet
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Pentium
II processor frequencies and cache sizes.
2. Not 100% tested. Specified by design characterization.
3. All AC timings for AGTL+ signals are referenced to the BCLK rising edge at 0. 7 V at the processor edge fingers. All
AGTL+ signal timings (compatibility signals, etc.) are referenced at 1.00 V at the processor edge fingers.
4. Valid delay timings for these signals are specified into 50
to 1.5 V and with V
REF
at 1.0 V.
5. A minimum of 3 clocks must be guaranteed between two active-to-inactive transitions of TRDY#.
6. RESET# can be asserted (active) asynchronously, but must be deasserted synchronously.
7. Specification is for a minimum 0.40 V swing.
8. Specification is for a maximum 1.0 V swing.
9. After V

CORE
, V
CC
L2
, and BCLK become stable.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Pentium
II processor frequencies and cache sizes.
2. These specifications are tested during manufacturing.
3. All AC timings for the AGTL+ signals are referenced to the BCLK rising edge at 1.25 V at the processor core pin. All
AGTL+ signal timings (compatibility signals, etc.) are referenced at 1.00 V at the processor core pins.
4. Valid delay timings for these signals are specified into 25
to 1.5 V and with VREF at 1.0 V.
5. A minimum of 3 clocks must be guaranteed between two active-to-inactive transitions of TRDY#.
6. RESET# can be asserted (active) asynchronously, but must be deasserted synchronously.
7. Specification is for a minimum 0.40 V swing.
8. Specification is for a maximum 1.0 V swing.
9. This should be measured after V
CC
CORE
, V
CCL2
, and BCLK become stable.
