Description
The Atmel® AT25080B/160B provides 8,192/16,384 bits of Serial Electrically-
Erasable Programmable Read-Only Memory (EEPROM) organized as
1,024/2,048 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 AT25080B/160B is available in space-saving 8-lead
JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN, 8-pad XDFN, 8-ball VFBGA, and
8-ball WLCSP packages.
The AT25080B/160B is enabled through the Chip Select pin (CS) and accessed
via a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO),
and Serial Clock (SCK). All programming cycles are completely 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.
