... When the device is deselected, the CMOS standby current is less than 100 A. For the AT49F002N(T) pin 1 for the DIP and PLCC packages and pin 9 for the TSOP package are don’t connect pins. To allow for simple in-system reprogrammability, the AT49F002(N)(T) does not require high input voltages for programming ...
