Description  
The AT28BV64 is a low-voltage, low-power Electrically Erasable and Programmable  
Read Only Memory specifically designed for battery powered applications. Its 64K of  
memory is organized 8,192 words by 8 bits. Manufactured with Atmel’s advanced  
nonvolatile CMOS technology, the device offers access times to 200 ns with power  
dissipation less than 30 mW. When the device is deselected the standby current is  
less than 50 µA.  
The AT28BV64 is accessed like a Static RAM for the read or write cycles without the  
need for external components. During a byte write, the address and data are latched  
internally, freeing the microprocessor address and data bus for other operations. Fol-
