Name and Function
Device Core Power Supply:
Core (logic) source voltage. Writes to the flash array are inhibited
when V
CC
≤
V
LKO
. Operations at invalid V
CC
voltages should not be attempted.
Output Power Supply:
Output-driver source voltage.
Ground:
Connect to system ground. Do not float any VSS connection.
Reserved for Future Use:
Reserved by Numonyx 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.
