25AA640-I/SN

The 25AA640-I/SN, also known as an EEPROM, is a memory IC from Microchip Technology. It is a 1.8V Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) with a 8k-byte capacity. It operates with an I2C bus interface and has a maximum write cycle of 10,000. The 25AA640-I/SN is uniquely identified by its serial number, which is provided on the individual serial numbers label on the product itself.

The 25AA640-I/SN is designed to store and process data in a variety of applications. It is commonly used in mobile devices, such as cell phones, tablet computers and PDAs. It is also used in industrial and automotive applications, as well as in other areas such as healthcare, telecommunications and consumer electronics. Additionally, the 25AA640-I/SN is ideal for applications such as memory security, system monitoring, data acquisition and storage.

From a working principle perspective, the 25AA640-I/SN is an asynchronous device that stores its data with 13 levels of protection that ensure the data stays secure. It is connected to the I2C bus and receives commands from a host. When the host sends a command, the 25AA640-I/SN will respond accordingly. It can be programmed and read in the same way that a ROM does. It allows for single- or multiple-byte reads and writes. The 25AA640-I/SN has two hardware clock pins, which can be used to synchronize external devices to its internal clock. Additionally, it has an interrupt pin that can be used to receive an interrupt whenever data is written to or read from the device.

In summary, the 25AA640-I/SN is a 1.8V Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) with a 8k-byte capacity. It has a wide range of application fields, such as mobile devices, industrial and automotive applications and other fields. It operates with an I2C bus interface and has 13 levels of protection to ensure the secure storage of data. It also has two hardware clock pins and an interrupt pin that can be used to synchronize external devices and receive interrupts whenever data is written or read. The 25AA640-I/SN is an ideal memory solution for various applications.
