Description  
The AT28HC64B is a high-performance electrically erasable and programmable read  
only memory (EEPROM). Its 64K of memory is organized as 8,192 words by 8 bits.  
Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers  
access times to 55 ns with power dissipation of just 220 mW. When the device is  
deselected, the CMOS standby current is less than 100 µA.  
The AT28HC64B is accessed like a Static RAM for the read or write cycle without the  
need for external components. The device contains a 64-byte page register to allow
