NOTES:
1. All currents are in RMS unless otherwise noted. Typical values at V
CC
= 5.0V, V
PP
=12.0V , T = +25°C. These currents are
valid for all product versions (packages and speeds).
2. I
CCES
is specified with the device de-selected. If the device is read while in erase suspend mode, current draw is the sum of
I
CCES
and I
CCR
.
3. Block erases and byte writes are inhibited when V
PP
= V
PPLK
, and not guaranteed in the range between V
PPH
and V
PPLK
.
4. Sampled, not 100% tested.
5. CMOS Inputs are either V
CC
± 0.2V or GND ± 0.2V. TTL Inputs are either V
IL
or V
IH
.
6. V
CC
= 12.0V ± 10% for applications requiring 100,000 block erase cycles.
7. V
PP
= 12.0V ± 5% for applications requiring 100,000 block erase cycles.
8.
V
= 12.0V ± 10% for applications requiring wider V
tolerances: Parameter blocks can sustain 10,000 block erase
cycles; main blocks support up to 100 block erase cycles. Note that erase times are close to maximum spec limits when
using this option.
