Description

The AT25F1024A provides 1,048,576 bits of serial reprogrammable Flash memory organized as 131,072 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 AT25F1024A is available in a space-saving 8-lead JEDEC SOIC and 8-lead SAP packages.

The AT25F1024A 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 write cycles are completely self-timed.
