Preliminary

DC Characteristics, Continued

NOTES:

1. All currents are in RMS unless otherwise noted. These currents are valid for all product versions (packages

and speeds). Contact Intel’s Application Support Hotline or your local sales office for information about typical

specifications.

2. Includes STS.

3. CMOS inputs are either VCC ± 0.2 V or GND ± 0.2 V. TTL inputs are either VIL or VIH.

4. Current values are specified over the temperature range (0 °C to 70 °C) and may increase slightly at –25 °C.

5. Sampled, not 100% tested.

6. ICCWS and ICCES are specified with the device de-selected. If the device is read or written while in erase

suspend mode, the device’s current draw is ICCR or ICCW.

7. Block erases, programming, and lock-bit configurations are inhibited when VPEN ≤ VPENLK, and not

guaranteed in the range between VPENLK (max) and VPENH (min), and above VPENH (max).

8. Typically, VPEN is connected to VCC (2.7 V–3.6 V).

9. Block erases, programming, and lock-bit configurations are inhibited when VCC < VLKO, and not guaranteed

in the range between VLKO (min) and VCC (min), and above VCC (max).

NOTE: AC test inputs are driven at VCCQ for a Logic "1" and 0.0 V for a Logic "0." Input timing begins, and

output timing ends, at VCCQ/2 V (50% of VCCQ). Input rise and fall times (10% to 90%) < 5 ns.
