Product Summary

The AT29C040A-90TU is a 5-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 AT29C040A-90TU offers access times up to 90 ns, and a low 220 mW power dissipation. When the device is deselected, the CMOS standby current is less than 100 μA. The AT29C040A-90TU endurance is such that any sector can typically be written to in excess of 10,000 times. To allow for simple in-system reprogrammability, the AT29C040A-90TU does not require high input voltages for programming. Five-volt-only commands determine the operation of the device. Reading data out of the device is similar to reading from an EPROM.
