Processor up to 1.10 GHz
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all Celeron processor frequencies.
2. For the S.E.P. and PPGA packages: All AC timings for the TAP signals are referenced to the TCK rising edge
at 1.25 V at the processor core pins. All TAP signal timings (TMS, TDI, etc.) are referenced at 1.25 V at the
processor core pins.
For the FC-PGA/FC-PGA2 packages: All AC timings for the TAP signals are referenced to the TCK rising
edge at 0.75 V at the processor pins. All TAP signal timings (TMS, TDI, etc.) are referenced at 0.75 V at the
processor pins.
3. These specifications are tested during manufacturing, unless otherwise noted.
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. For the S.E.P. and PPGA packages: Valid delay timing for this signal is specified to 2.5 V +5%.
For the FC-PGA/FC-PGA2 packages: Valid delay timing for this signal is specified to 1.5 V +3%.
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.
10.Not 100% tested. Specified by design characterization.
