Description
2
The NV24C512WF is a EEPROM Serial 512−Kb I C, internally
organized as 65,536 words of 8 bits each.
It features a 128−byte page write buffer and supports the Standard
(100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I C protocol.
Write operations can be inhibited by taking the WP pin High (this
protects the entire memory).
External address pins make it possible to address up to eight
NV24C512WF devices on the same bus.
