It appears that the part you are referring to, AT25256B-SSHL-T, is a specific component. Based on the name, AT25256B is likely a product from Atmel (now part of Microchip Technology), and the suffix SSHL-T typically refers to a specific package type (such as a TSSOP or another surface-mount package).
I'll provide the requested pinout and function table in a detailed manner based on the information available for this type of chip. However, since I cannot search the web, I will give you an outline and example, focusing on general characteristics for similar components (such as EEPROM chips) and how to structure the pinout and FAQ section. This should give you a starting point for further research or for crafting the detailed table you're asking for.
