... Read The AT29C512 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. This dual-line control gives designers flexibility in preventing bus contention ...

... CE or WE. The 128 bytes of data must be loaded into each sector by the same procedure as outlined in the program section under device operation. 4.5 Hardware Data Protection Hardware features protect against inadvertent programs to the AT29C512 in the following ways: ( delay – once V (typical) before programming ...

... Toggle Bit In addition to DATA polling the AT29C512 provides another method for determining the end of a program 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. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read ...
