Exposure to absolute maximum rating onditions for extended periods may affect evice reliability.

The AT28C010-12DK is a high-performance Electrically Erasable and Programmable ead-Only Memory. Its one megabit of memory is organized as 131,072 words by 8 its. Manufactured with Atmel's advanced nonvolatile CMOS technology, the device ffers access times to 120 ns with power dissipation of just 440 mW. When the device s deselected, the CMOS standby current is less than 300 A.

The AT28C010-12DK is accessed like a Static RAM for the read or write cycle without he need for external components. The AT28C010-12DK contains a 128-byte page register to llow writing of up to 128 bytes simultaneously. During a write cycle, the address and  to 128 bytes of data are internally latched, freeing the address and data bus for ther operations. Following the initiation of a write cycle, the device will automatically rite the latched data using an internal control timer. The end of a write cycle can be etected by DATA POLLING of I/O7. Once the end of a write cycle has been detected  new access for a read or write can begin.

Atmel's AT28C010-12DKhas additional features to ensure high quality in manufacturing. The AT28C010-12DK utilizes internal error correction for extended endurance and improved data  etention characteristics. An optional software data protection mechanism is available o guard against inadvertent writes. The AT28C010-12DK also includes an extra 128 bytes of EPROM for device identification or tracking.
