AT25512
Description
The AT25512 provides 524,288 bits of serial electrically-erasable programmable read
only memory (EEPROM) organized as 65,536 words of 8 bits each. The device is opti-
mized 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
JEDEC SOIC, 8-lead TSSOP and 8-lead SAP packages. In addition, the entire family
is available in 1.8V (1.8V to 5.5V) versions.
The AT25512 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 top ¼, top ½ or entire
array of write protection. Separate Program Enable and Program Disable instructions are pro-
vided 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.
