... Commercial and Industrial Temperature Ranges Description The AT28LV64B is a high-performance electrically erasable programmable read only memory (EEPROM). Its 64K of memory is organized as 8,192 words by 8 bits. Manu- factured 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 µ ...

... The AT28LV64B 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 writing bytes simultaneously. During a write cycle, the addresses and bytes of data are internally latched, freeing the address and data bus for other operations. Fol- lowing the initiation of a write cycle, the device will automat- ically write the latched data using an internal control timer ...

... DATA Polling may begin at anytime during the write cycle. TOGGLE BIT: In addition to DATA Polling, the AT28LV64B provides another method for determining the end of a write cycle. During the write operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero ...
