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 V
CC
 ± 0.2 V or GND ± 0.2 V. TTL inputs are either V
IL
 or V
IH
. 
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. I
CCWS
 and I
CCES
 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 I
CCR
 or I
CCW
.
7. Block erases, programming, and lock-bit configurations are inhibited when V
PEN
≤
 V
PENLK
, and not 
guaranteed in the range between V
PENLK 
(max) and V
PENH 
(min), and above V
PENH 
(max).
8. Typically, V
PEN
 is connected to V
CC
 (2.7 V
–
3.6 V).
9. Block erases, programming, and lock-bit configurations are inhibited when V
CC
 < V
LKO
, and not guaranteed 
in the range between V
LKO 
(min) and V
CC 
(min), and above V
CC 
(max).
NOTE:
 AC test inputs are driven at V
 for a Logic "1" and 0.0 V for a Logic "0." Input timing begins, and 
output timing ends, at V
CCQ
/2 V (50% of V
CCQ
). Input rise and fall times (10% to 90%) < 5 ns.
