... Five-volt-only commands determine the opera- tion of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT29C010A is performed on a sector basis; 128 bytes of data are loaded into the device and then simultaneously programmed. ...

... Device Operation 4.1 Read The AT29C010A 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 con- trol gives designers flexibility in preventing bus contention ...

... DATA Polling The AT29C010A features DATA polling to indicate the end of a program cycle. During a pro- gram cycle an attempted read of the last byte loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin ...

... These two 8K memory sections are referred to as boot blocks. Secure code which will bring up a system can be contained in a boot block. The AT29C010A blocks are located in the first 8K bytes of memory and the last 8K bytes of memory. The boot block programming lockout feature can therefore support systems that boot from the lower addresses of memory or the higher addresses ...
