... Commercial and Industrial Temperature Ranges Description The AT29BV040A is a 3-volt-only in-system Flash Programmable and Erasable Read Only Memory (PEROM). Its 4 megabits of memory is organized as 524,288 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS EEPROM technology, the device offers access times to 200 ns, and a low 54 mW power dissipation. When the device is deselected, the CMOS standby current is less than 40 µ ...

... SOFTWARE DATA PROTECTION PROGRAMMING: The AT29BV040 has 2048 indi- vidual sectors, each 256 bytes. Using the software data protection feature, byte loads are used to enter the 256 bytes of a sector to be programmed. The AT29BV040A 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 AT29BV040A features DATA polling to indicate the end of a program 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 ...

... These two 16K memory sections are referred to as boot blocks. Secure code which will bring up a system can be contained in a boot block. The AT29BV040A blocks are located in the first 16K bytes of memory and the last 16K 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 ...
