25AA080A/B

      The memory of 25AA080A/B and 25LC080A/B(8K SPI Bus Serial EEPROM)  is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to 25AA080A/B and 25LC080A/B is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of chip select, allowing the host to service higher priority interrupts.
      The 25AA080A/B and 25LC080A/B are available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, and 8-lead TSSOP. All packages are Pb-free and RoHS compliant.
      The 25AA080A/B and 25LC080A/B have the traits of Low-power CMOS technology, Max. clock 10 MHz, 1024 x 8-bit organization, 32 byte page ('B' version devices), 16 byte page ('A' version devices), Self-timed ERASE and WRITE cycles, Write cycle time: 5 ms max, Block write protection(Protect none, 1/4, 1/2 or all of array), Built-in write protection(Power-on/off data protection circuitry, Write enable latch, Write-protect pin), High reliability(Endurance: 1,000,000 erase/write cycles, Data retention: > 200 years, ESD protection: > 4000V), Pb-free and RoHS compliant, Sequential read, Temperature ranges supported(Industrial (I): -40°Cto +85°C, Automotive (E): -40°C to +125°C).
And the parameter of the 25AA080A/B and 25LC080A/B in the electrite are VCC(7.0V), All inputs and outputs w.r.t. VSS(-0.6V to VCC +1.0V ), Storage temperature(-65°C to 150°C), Ambient temperature under bias(-65°C to 125°C), ESD protection on all pins(4 kV).
