Datasheet 45
Intel
®
Celeron
®
Processor up to 1.10 GHz
NOTES:
1. Unless otherwise noted, all specifications in this table apply to Celeron processors at all frequencies.
2. These specifications are tested during manufacturing.
3. All AC timings for the APIC I/O signals are referenced to the PICCLK rising edge at 1.25 V at the processor
pins. All APIC I/O signal timings are referenced at 0.75 V at the processor pins.
4. Referenced to PICCLK rising edge.
5. For open drain signals, valid delay is synonymous with float delay.
6. Valid delay timings for these signals are specified into 150 Ω load pulled up to 1.5 V.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Intel
®
Celeron
®
processor frequencies.
2. All AC timings for the TAP signals are referenced to the TCK rising edge at 0.70 V at the processor edge
fingers. All TAP signal timings (TMS, TDI, etc.) are referenced at 1.25 V at the processor edge fingers.
3. Not 100% tested. Specified by design characterization.
4. 1 ns can be added to the maximum TCK rise and fall times for every 1 MHz below 16.667 MHz.
5. Referenced to TCK rising edge.
6. Referenced to TCK falling edge.
7. Valid delay timing for this signal is specified to 2.5 V +5%.
8. Non-Test Outputs and Inputs are the normal output or input signals (besides TCK, TRST#, TDI, TDO, and
TMS). These timings correspond to the response of these signals due to TAP operations.
9. During Debug Port operation, use the normal specified timings rather than the TAP signal timings.
