... AT49F8192A(T) Block Diagram ADDRESS Device READ: The AT49F008A(T)/8192A(T) 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 Operation asserted on the outputs. The outputs are put in the high-impedance state whenever high ...

... This feature does not have to be activated; the boot block’s usage as a write-protected region is optional to the user. The address range of the boot block is 00000H to 03FFFH for the AT49F008A; FC000H to FFFFFH for the AT49F008AT; 00000H to 01FFFH for the AT49F8192A; and 7E000H to 7FFFFH for the AT49F8192AT. ...

Software Product Identification Entry and Exit sections), a read from the following address location will show if programming the boot block is locked out – 00002H for the AT49F008A and AT49F8192A; FC002H for the AT49F008AT; and 7E002H for the AT49F8192AT. If the data on I/O0 is low, the boot block can be programmed; if the data on I/O0 is high, the program lockout feature has been enabled and the block cannot be pro- grammed ...
