Features
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 µA. The device endurance is such that any sector can typically be written to in
excess of 10,000 times.

... 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 ...

Page 4

... 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 ...
