Description  
The AT49BV/LV4096A is a 3-volt, 4-megabit Flash memory organized as 524,288  
words of 8 bits each or 256K words of 16 bits each. Manufactured with Atmel’s  
advanced nonvolatile CMOS technology, the device offers access times to 70 ns with  
power dissipation of just 67 mV at 2.7V read. When deselected, the CMOS standby  
current is less than 50 µA.  
The device contains a user-enabled “boot block” protection feature. The  
AT49BV/LV4096A locates the boot block at lowest order addresses (“bottom boot”).  
AT49BV4096A  
AT49LV4096A  
To allow for simple in-system reprogrammability, the AT49BV/LV4096A does not  
require high input voltages for programming. Reading data out of the device is similar  
to reading from an EPROM; it has standard CE, OE and WE inputs to avoid bus con-  
tention. Reprogramming the AT49BV/LV4096A is performed by first erasing a block of  
data and then programming on a byte-by-byte or word-by-word basis.
