... When deselected, the CMOS standby current is less than 100 µA. To allow for simple in-system reprogrammability, the AT49F2048A does not require high input voltages for pro- gramming. 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; it has standard CE, OE and WE inputs to avoid bus connec- tion ...

... Data Polling may begin at any time during the program cycle. TOGGLE BIT: In addition to Data Polling, the AT49F2048A provides another method for determining the end of a pro- gram or erase cycle. During a program or erase operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero ...
