Product Summary

The AT29LV040A15TU 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 advanced nonvolatile CMOS EEPROM technology, the AT29LV040A15TU offers access times to 150 ns, and a low 54 mW power dissipation. When the AT29LV040A15TU is deselected, the CMOS standby current is less than 50 μA. The device endurance is such that any sector can typically be written to in excess of 10,000 times. The programming algorithm is compatible with other devices in Atmel 3-volt only Flash memories. Reprogramming the AT29LV040A15TU is performed on a sector basis; 256 bytes of data are loaded into the device and then simultaneously programmed.
