Description
The AT28LV256 is a high-performance Electrically Erasable and Programmable
Read Only Memory. Its 256K of memory is organized as 32,768 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 200
μ
A.
The AT28LV256 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 of up to 64-bytes simultaneously. During a write cycle, the addresses and 1 to
