AT25F4096
Description
The AT25F4096 provides 4,194,304 bits of serial reprogrammable Flash memory
organized as 524,288 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 AT25F4096 is available in a space-saving 8-lead EIAJ SOIC and 8-
lead SAP packages.
