are essential. The AT25080/160/320/640 is available in

space saving 8-pin PDIP, JEDEC SOIC, and 14-pin and

20-pin TSSOP packages.

The AT25080/160/320/640 is enabled through the Chip

Select pin (CS) and accessed via a 3-wire interface con-

sisting of Serial Data Input (SI), Serial Data Output (SO),

and Serial Clock (SCK). All programming cycles are com-

pletely self-timed, and no separate ERASE cycle is

required before WRITE.

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 suspend any serial communication

without resetting the serial sequence.
