... When the device is deselected, the CMOS standby current is less than 50 µA. For the AT49BV001AN(T), pin 1 for the PLCC package and pin 9 for the TSOP package are no con- nect pins. To allow for simple in-system reprogrammability, the AT49BV001A(N)(T) does not require high input voltages for programming. Five-volt-only commands determine the read and programming operation of the device. Reading data out of the device is similar to reading from an EPROM ...
