Description
The AT28LV010 is a high-performance 3-volt only Electrically Erasable and Program-
mable Read Only Memory. Its 1 megabit of memory is organized as 131,072 words
by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the
device offers access times to 200 ns with power dissipation of just 54 mW. When the
device is deselected, the CMOS standby current is less than 20 A.

... Description (Continued) The AT28LV010 is accessed like a Static RAM for the read or write cycle without the need for external compo- nents. The device contains a 128-byte page register to al- low writing 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 ...

... high. This dual- line control gives designers flexibility in preventing bus contention in their system. WRITE: The write operation of the AT28LV010 allows 1 to 128-bytes of data to be written into the device during a single internal programming period. Each write operation must be preceded by the software data protection (SDP) command sequence ...
