NOTES:
1. All currents are in RMS unless otherwise noted.
2. CMOS inputs are either VCC ± 0.2 V or GND ± 0.2 V. TTL inputs
are either VIL or VIH.
3. Automatic Power Savings (APS) reduces typical ICCR to 3 mA at
3.3 V VCC in static operation.
4. Sampled, not 100% tested.
5. ICCWS and ICCES are specified with the device de-selected. If read
or word written while in erase suspend mode, the device’s current
draw is the sum of ICCWS or ICCES and ICCR or ICCW, respectively.
6. Block erases and word writes are inhibited when VPP ≤ VPPLK,
and not guaranteed in the range between VPPLK (MAX.) and
VPPH (MIN.).
7. Block erases and word writes are inhibited when the correspond-
ing RP = VIH or WP = VIL. Block erase and word write operations
are not guaranteed with VCC < 3.0 V or VIH < RP < VHH and
should not be attempted.
8. RP connection to a VHH supply is allowed for a maximum cumu-
lative period of 80 hours.
