AT25080A_07 Datasheet, PDF (2/24 Pages) ATMEL Corporation – SPI Serial EEPROMs

Block write protection is enabled by programming the status register with one of four blocks of
write protection. Separate program enable and program disable instructions are provided for
additional data protection. Hardware data protection is provided via the WP pin to protect
against inadvertent write attempts to the status register. The HOLD pin may be used to sus-
pend any serial communication without resetting the serial sequence.
