... Commercial and Industrial Temperature Ranges Description The AT29LV512 is a 3-volt-only in-system Flash programmable erasable read-only memory (PEROM). Its 512K of memory is organized as 65,536 words by 8 bits. Man- ufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 120 ns with power dissipation of just 54 mW over the commercial tem- perature range. When the device is deselected, the CMOS standby current is less than 40 µ ...

... SOFTWARE DATA PROTECTION PROGRAMMING: The AT29LV512 has 512 individ- ual sectors, each 128 bytes. Using the software data protection feature, byte loads are used to enter the 128 bytes of a sector to be programmed. The AT29LV512 can only be programmed or reprogrammed using the software data protection feature. The device is programmed on a sector basis ...

... For details, see Operating Modes (for hardware operation) or Software Product Identifi- cation. The manufacturer and device code is the same for both modes. DATA POLLING: The AT29LV512 features DATA polling to indicate the end of a pro- gram cycle. During a program cycle an attempted read of the last byte loaded will result in the complement of the loaded data on I/O7 ...

... TOGGLE BIT: In addition to DATA polling the AT29LV512 provides another method for determining the end of a program or erase cycle. During a program or erase opera- tion, 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 ...
