The 25AA040T/SN is a 4 kilobit (512 bytes) SPI serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device. It provides the advantage of electrically erasable code storage with the high performance of an integrated circuit. This nonvolatile memory device incorporates an on-board write protect to prevent accidental erasure or alteration of data stored in its memory. The 25AA040T/SN can be written to or read from with an easy to use SPI/QSPI protocol.

The 25AA040T/SN is used in many applications such as data logging, asset tracking, environmental monitoring, home automation and security systems. Most microcontroller projects benefit from the 25AA040T/SN due to its nonvolatile behavior and high reliability. For example, developers often need to store information in the microcontroller’s programs that needs to be preserved even after the power is turned off. This data can be stored in the 25AA040T/SN and can be accessed by the microcontroller as and when needed.

The 25AA040T/SN is also a useful tool for communication interface applications. It can be used to store received data or to respond to commands initiated by the communication interface. The memory can also be used to store parameters or settings related to the communication. Since this memory device is nonvolatile, it is an ideal storage medium for these types of applications.

The 25AA040T/SN operates as a single supply memory device with a power supply voltage ranging from 2.7 volts to 5.5 volts. Its SPI/QSPI protocol allows for easy and efficient data communication between the device and a controller. The device is capable of transferring data in both directions, writing and reading data from memory. The device has an onboard write protect, which is provided by the Protect zone pin and allows for write protection of the entire memory array or various blocks of memory.

The 25AA040T/SN is a powerful memory device that is capable of storing up to 512 bytes of data. It is an easy to use and highly reliable device that is ideal for applications where data storage and retrieval needs to be done reliably and quickly. With its nonvolatile ability, it can be used to store data that needs to be preserved even when the power is off.
