Description  
The AT49F512 is a 5-volt-only in-system programmable and erasable Flash Memory.  
Its 512K of memory is organized as 65,536 words by 8 bits. Manufactured with  
Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 70  
ns with a power dissipation of just 165 mW over the commercial temperature range.  
When the device is deselected, the CMOS standby current is less than 100 µA.  
AT49F512  
To allow for simple in-system reprogrammability, the AT49F512 does not require high  
input voltages for programming. Five-volt-only commands determine the read and  
programming operation of the device. Reading data out of the device is similar to  
reading from an EPROM. Reprogramming the AT49F512 is performed by erasing the  
entire 512K of memory and then programming on a byte by byte basis. The typical  
byte programming time is a fast 10 µs. The end of a program cycle can be optionally
