Description  
The AT49F004(T) and AT49F4096A(T) are 5-volt, 4-megabit Flash Memories orga-  
nized as 524,288 words of 8 bits each or 256K words of 16 bits each. Manufactured  
with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times  
to 55 ns with power dissipation of just 275 mW. When deselected, the CMOS standby  
current is less than 300 µA.

Preliminary  
The device contains a user-enabled “boot block” protection feature. Two versions of  
the feature are available: the AT49F004/4096A locates the boot block at lowest order  
addresses (“bottom boot”); the AT49F004T/4096AT locates it at highest order  
addresses (“top boot”).  
To allow for simple in-system reprogrammability, the AT49F004(T)/4096A(T) 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 AT49F004(T)/4096A(T) is performed by first erasing a
