Description
The AT25128B/256B provides 131,072/262,144 bits of serial electrically-erasable pro-
grammable read only memory (EEPROM) organized as 16,384/32,768 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 devices are available
in space saving 8-lead SOIC, 8-lead TSSOP, 8-ball VFBGA and 8-lead UDFN pack-
ages. In addition, the entire family is available in 1.8V (1.8V to 5.5V).
The AT25128B/256B 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 sepa-
rate Erase cycle is required before Write.
Block Write protection is enabled by programming the status register with top , top
or entire array 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 reg-
ister. The HOLD pin may be used to suspend any serial communication without
resetting the serial sequence.
