1. Description  
The AT28C64E is a low-power, high-performance 8,192 words by 8-bit nonvolatile  
electrically erasable and programmable read-only memory with popular, easy-to-use  
features. The device is manufactured with Atmel’s reliable nonvolatile technology.  
The AT28C64E 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-  
lowing the initiation of a write cycle, the device will go to a busy state and  
automatically clear and write the latched data using an internal control timer. The  
device includes two methods for detecting the end of a write cycle, level detection of  
RDY/BUSY (unless pin 1 is N.C.) and DATA Polling of I/O7. Once the end of a write  
cycle has been detected, a new access for a read or write can begin.  
The CMOS technology offers fast access times of 120 ns at low power dissipation.  
When the chip is deselected, the standby current is less than 100 µA.  
Atmel’s AT28C64E has additional features to ensure high quality and manufacturabil-  
ity. The device utilizes error correction internally for extended endurance and for  
improved data retention characteristics. An extra 32 bytes of EEPROM are available  
for device identification or tracking.
