WRITE PROTECT: Active low input. WP# low enables the lock-down mechanism. Blocks in lock-
down cannot be unlocked with the Unlock command. WP# high overrides the lock-down function
enabling blocks to be erased or programmed using software commands.
Erase and Program Power: A valid voltage on this pin allows erasing or programming. Memory
contents cannot be altered when V
should not be attempted.

cycles. VPP can be connected to 9 V for a cumulative total not to exceed 80 hours. Extended use of
this pin at 9 V may reduce block cycling capability.
Device Core Power Supply: Core (logic) source voltage. Writes to the flash array are inhibited when

Output Power Supply: Output-driver source voltage.
Ground: Connect to system ground. Do not float any VSS connection.
Reserved for Future Use: Reserved by Intel for future device functionality and enhancement. These
should be treated in the same way as a Do Not Use (DU) signal.
Do Not Use: Do not connect to any other signal, or power supply; must be left floating.
No Connect: No internal connection; can be driven or floated.
