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 ac-
cess times to 200 ns with power dissipation of just 54 mW. When the device is dese-
lected, the CMOS standby current is less than 20
μ
A.
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
