Description  
The AT34C02B provides 2048 bits of serial electrically-erasable and programmable  
read only memory (EEPROM) organized as 256 words of 8 bits each. The first-half of  
the device incorporates a permanent and a reversible software write protection feature  
while hardware write protection for the entire array is available via an external pin.  
Once the permanent software write protection is enabled, by sending a special com-  
mand to the device, it cannot be reversed. However, the reversible software write  
protection is enabled and can be reversed by sending a special command. The hard-  
ware write protection is controlled with the WP pin and can be used to protect the  
entire array, whether or not the software write protection has been enabled. This  
allows the user to protect none, first-half, or all of the array depending on the applica-  
tion. The device is optimized for use in many industrial and commercial applications  
where low-power and low-voltage operations are essential. The AT34C02B is avail-  
able in space saving 8-lead JEDEC SOIC, 8-lead Ultra Thin Mini-MAP (MLP 2x3), 8-lead  
TSSOP, and 8-ball dBGA2 packages and is accessed via a Two-wire serial interface.  
It is available in 1.7V (1.7V to 3.6V).
