The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT25F512A is available in a space-saving 8-lead JEDEC SOIC and 8-lead SAP packages. The AT25F512A is enabled through the Chip Select pin (CS) and accessed via a three-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All write cycles are completely self-timed. Block write protection for the...
