Product Summary

The AT29C020-90JU is a 5-volt-only in-system Flash programmable and erasable read-only memory (PEROM). Its 2 megabits of memory is organized as 262,144 bytes. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 70 ns with power dissipation of just 220 mW over the industrial temperature range. When the device is deselected, the CMOS standby current is less than 300 µA. Device 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 AT29C020-90JU 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. Reprogramming the AT29C020-90JU is performed on a sector basis; 256 bytes of data are loaded into the device and then simultaneously programmed.
