NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Celeron processor frequencies.
2. Not 100% tested. Specified by design characterization.
3. All AC timings for the CMOS signals are referenced to the BCLK rising edge at 0.50 V at the processor edge
fingers. All CMOS signal timings (address bus, data bus, etc.) are referenced at 1.25 V.
4. These signals may be driven asynchronously.
5. This specification only applies when the APIC is enabled and the LINT1 or LINT0 pin is configured as an
edge-triggered interrupt with fixed delivery; otherwise, specification T14 applies.
PWRGOOD must remain below V_IL,max (Table 6) until all the voltage planes meet the voltage tolerance
specifications in Table 5 and BCLK has met the BCLK AC specifications in Table 10 for at least 10 clock
cycles. PWRGOOD must rise glitch-free and monotonically to 2.5 V.
6. When driven inactive or after VCCCORE, and BCLK become stable.
7. If the BCLK signal meets its AC specification within 150 ns of turning on, then the PWRGOOD inactive pulse
width specification (T15) is waived and BCLK may start after PWRGOOD is asserted. PWRGOOD must still
remain below V_IL,max until all the voltage planes meet the voltage tolerance specifications.
