... 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. Reprogramming the AT49F512 is performed by erasing the entire 512K of memory and then programming on a byte by byte basis. The typical byte programming time is a fast 10 µ ...

... Block Diagram Device Operation READ: The AT49F512 is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the high impedance state whenever high ...

... Respect to Ground ...................................-0.6V to +13.5V outputs and the next cycle may begin. DATA polling may begin at any time during the program cycle. TOGGLE BIT: In addition to DATA polling the AT49F512 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 ...
