Description
The AT25080/160/320/640 provides 8192/16384/32768/65536 bits of serial electri-
cally erasable programmable read only memory (EEPROM) organized as
1024/2048/4096/8192 words of 8 bits each. The device is optimized for use in many
industrial and commercial applications where low power and low voltage operation

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.
