Description  
The AT49F4096A is a 5-volt, 4-megabit Flash memory organized as 524,288 words of  
8 bits each or 256K words of 16 bits each. Manufactured with Atmels advanced non-  
volatile CMOS technology, the device offers access times to 55 ns with power dissi-  
pation of just 275 mW. When deselected, the CMOS standby current is less than  
300 µA.  
AT49F4096A  
The device contains a user-enabled boot blockprotection feature. The AT49F4096A  
locates the boot block at lowest order addresses (bottom boot).  
To allow for simple in-system reprogrammability, the AT49F4096A does not require  
high input voltages for programming. Reading data out of the device is similar to read-  
ing from an EPROM; it has standard CE, OE, and WE inputs to avoid bus contention.  
Reprogramming the AT49F4096A is performed by first erasing a block of data and  
then programming on a byte-by-byte or word-by-word basis.
