1. I
2. Typical values are measured at V
3. Operating supply currents and burst mode currents are measured at 100 percent bus utilization.
4. NOP currents are valid when entering NOP after all pending READ and WRITE cycles are completed.
5. Average I/O current and power is provided for information purposes only and is not tested. Calculation assumes that all outputs are
6. This parameter is sampled.
7. Average thermal resistance between the die and the case top surface per MIL SPEC 883 Method 1012.1.
8. Junction temperature is a function of total device power dissipation and device mounting environment. Measured per SEMI G38-
