Description  
The AT49F080 is a 5-volt-only in-system Flash Memory device. Its 8-megabits of  
memory is organized as 1,024,576 words by 8-bits. Manufactured with Atmel’s  
advanced nonvolatile CMOS technology, the device offers access times to 90 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.  
Memory  
AT49F080  
AT49F080T  
The device contains a user-enabled “boot block” protection feature. Two versions of  
the feature are available: the AT49F080 locates the boot block at lowest order  
addresses (“bottom boot”); the AT49F080T locates it at highest order addresses (“top  
boot”).
