Features
Description
The AT49F1024 and the 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
