The AT49F1024 and AT49F1025 are 5-volt-only in-system Flash memories. Their 1 megabit of memory is organized as 65,536 words by 16 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 35 ns with power dissipation of just 275 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 100 µA. The only difference between the AT49F1024 and the AT49F1025 is the package. To allow for simple in-system reprogrammability, the AT49F1024/1025 does not require high-input voltages for programming. Five-volt-only commands determine the read/write operations.
