Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies and cache sizes.
2. Not 100% tested. Specified by design characterization.
3. All AC timings for the TAP signals are referenced to the TCK signal at 0.5 * Vcc at the processor pins. All TAP
signal timings (TMS, TDI, etc) are referenced at the 0.5 * Vcc processor pins.
4. Rise and fall times are measured from the 20% to 80% points of the signal swing.
5. Referenced to the rising edge of TCK.
6. Referenced to the falling edge of TCK.
7. Specification for a minimum swing defined between TAP 20% to 80%. This assumes a minimum edge rate of
0.5 V/ns
8. TRST# must be held asserted for 2 TCK periods to be guaranteed that it is recognized by the processor.
9. It is recommended that TMS be asserted while TRST# is being deasserted.
.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies and cache sizes.
2. These parameters are based on design characterization and are not tested.
3. All AC timings for the SMBus signals are referenced at VIL_MAX or VIH_MIN and measured at the processor
pins. Refer to Figure 16.
4. Minimum time allowed between request cycles.
5. Rise time is measured from (VIL_MAX - 0.15 V) to (VIH_MIN + 0.15 V). Fall time is measured from (0.9 *
SM_VCC) to (VIL_MAX - 0.15V). DC parameters are specified in Table 12.
