(TA = +25°C, F = 1.0MHZ)
Pin Configuration — 256K x 18
NOTES:
1. Pins 14, 64, and 66 do not have to be connected directly to VSS as long as the input voltage
is < VIL.
2. Pin 16 does not have to be connected directly to VDD as long as the input voltage
is > VIH.
3. Pins 83 and 84 are reserved for future 8M and 16M respectively.
4. Pin 64 supports ZZ (sleep mode) for the latest die revisions.

NOTE:
1. This parameter is guaranteed by device characterization, but not production tested.
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VDD terminals only.
3. VDDQ terminals only.
4. Input terminals only.
5. I/O terminals only.
6. This is a steady-state DC parameter that applies after the power supply has
reached its nominal operating value. Power sequencing is not necessary;
however, the voltage on any input or I/O pin cannot exceed VDDQ during power
supply ramp up.
7. TA is the "instant on" case temperature.
