... Green (Pb/Halide-free) Packaging Option 1. Description The AT29LV040A 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 150 ns, and a low 54 mW power dissipation. When the device is deselected, the CMOS standby current is less than 50 ...

... Device Operation 4.1 Read The AT29LV040A 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 AT29LV040A 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 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 AT29LV040A 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 ...
