AT28C010  
1. Description  
The AT28C010 is a high-performance electrically-erasable and programmable read-  
only memory. Its 1 megabit of memory is organized as 131,072 words by 8 bits. Man-  
ufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers  
access times to 120 ns with power dissipation of just 220 mW. When the device is  
deselected, the CMOS standby current is less than 200 µA.  
The AT28C010 is accessed like a Static RAM for the read or write cycle without the  
need for external components. The device contains a 128-byte page register to allow  
writing of up to 128 bytes simultaneously. During a write cycle, the address and 1 to  
128 bytes of data are internally latched, freeing the address and data bus for other  
operations. Following the initiation of a write cycle, the device will automatically write  
the latched data using an internal control timer. The end of a write cycle can be  
detected by 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.  
Atmel’s AT28C010 has additional features to ensure high quality and manufacturabil-  
ity. The device utilizes internal error correction for extended endurance and improved  
data retention characteristics. An optional software data protection mechanism is  
available to guard against inadvertent writes. The device also includes an extra  
128 bytes of EEPROM for device identification or tracking.
