The AT25080/160/320/640 is enabled through the Chip Select pin CS and accessed via a 3wire 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 one of four blocks 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 register. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence. Absolute Maximum Ratings* Operating -55°C to +125°C Storage Temperature -65°C to +150°C Voltage on Any Pin with Respect to Ground to +7.0V Maximum Operating Voltage 6.25V DC Output mA *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
