AT29C1024 is a 5-volt-only in-system Flash programmable and erasable read-only memory (PEROM). Its 1 megabit of memory is organized as 65,536 words by 16 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 70 ns with power dissipation of just 330 mW. When the device is deselected, the CMOS standby current is less than 200 µA. The device endurance is such that any sector can typically be written to in excess of 10,000 times.
The document describes the Atmel AT29C1024, a 1 megabit CMOS Flash PEROM organized as 65,536 words by 16 bits. It features fast read access times down to 70 ns and supports 5-volt-only reprogramming with sector-based programming operations.
The datasheet details device operation including read, data load, program, and chip erase modes. It also covers hardware and software data protection features, absolute maximum ratings, DC and AC operating ranges for various temperature grades (Commercial and Industrial), and pin configurations.
