Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. All outputs are open-drain.
3. Refer to I/O Buffer Models for I/V characteristics.
4. The V
CC
referred to in these specifications refers to instantaneous V
CC
.
5. The maximum output current is based on maximum current handling capability of the buffer and is not
specified into the test load shown in Figure 2-7.
6. Vol max of 0.320 V is guaranteed when driving into a test load of 50
Ω as indicated in Figure 2-7 for the TAP
Signals.
7. V
HYS
represents the amount of hysteresis, nominally centered about 1/2 V
CC
for all TAP inputs.
8. Leakage to V
SS
with pin held at V
CC
.
9. Leakage to V
CC
with Pin held at 300 mV.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. These parameters are not tested and are based on design simulations.
3. See Figure 2-6 for ITPCLKOUT[1:0] output buffer diagram.
