Description  
AT49BV4096  
AT49LV4096  
Not Recommended  
The AT49BV4096 and AT49LV4096 are 3-volt, 4-megabit Flash Memories organized  
as 256K words of 16 bits each. Manufactured with Atmel's advanced nonvolatile  
CMOS technology, the devices offer access times to 120 ns with power dissipation of  
just 67 mW at 2.7V read. When deselected, the CMOS standby current is less than  
50 µA.  
To allow for simple in-system reprogrammability, the AT49BV4096/LV4096 does not  
require high input voltages for programming. Reading data out of the device is similar
