NOTES:
1. VPPL may be grounded, a no-connect with a resistor tied
to ground, or < VCC + 2.0V. VPPH is the programming
voltage specified for the device. When VPP = VPPL,
memory contents can be read but not written or erased.
2. Manufacturer and device codes may also be accessed
via a command register write sequence. Refer to Table
1. All other addresses are low.
3. VID is the Silicon-ID-Read high voltage, 11.5V to 13V.
4. Read operations with VPP = VPPH may access array
data or Silicon ID codes.
5. With VPP at high voltage, the standby current equals ICC
+ IPP (standby).
6. Refer to Table 1 for valid Data-In during a write operation.
7. X can be VIL or VIH.
8. Includes D15
