AT24C08AN-10SI-2.5 Datasheet/PDFAT24C08AN-10SI-2.5 is a type of memory, which can be used for data storage. This memory device is based on the Serial Peripheral Interface (SPI) Bus Specification, which ensures both high speed and considerable data security. It is an 8-Kbit (1024 x 8) Electrically Erasable and Programmable Read Only Memory (EEPROM) device, which is ideal for embedded applications, such as data logging, motor control and remote device programming. In this article, the application field and working principle of AT24C08AN-10SI-2.5 will be discussed.
Application Field of AT24C08AN-10SI-2.5
The AT24C08AN-10SI-2.5 is mainly applied in the embedded design, data logging and remote device programming due to its small form factor and durable memory life. It is the ideal memory IC for 7-segment display, control interface, real-time clock and motor control applications. It is also used in real-time monitoring systems, such as GPS, security systems, healthcare and automation systems. Since the AT24C08AN-10SI-2.5 has a very low-power consumption, it can be used in battery-operated systems; it is suitable for microcontrollers and other slow circuits. Additionally, it can even be used in applications with extremely harsh temperature and humidity requirement. For example, AT24C08AN-10SI-2.5 can be used in automotive, industrial and medical environments.
Working Principle of AT24C08AN-10SI-2.5
AT24C08AN-10SI-2.5 is based on the Serial Peripheral Interface (SPI) Bus Specification and can communicate with the host controller via I2C, SPI or Microwire serial protocol. The communication protocol is used for controlling memory transaction and for exchanging the data between memory module and the host system. The SPI bus uses 4 wire connections (the SPI bus) for data exchange, namely the Clock (SCK), Master-Out/Slave-In (MOSI), Master-In/Slave-Out (MISO) and Slave select (SS) lines.
The memory module can be programmed, written and erased in the same way as conventional EEPROMs. Programming usually requires 3 clocks. First clock polarises the memory cell and sets its voltage to "0". The second clock sets the voltage level to "1", which is known as writing. The third clock sets the cell back to its original position, which is called erasing. After the programming is finished, the memory cell will retain its data even if power is removed.
AT24C08AN-10SI-2.5 also has a write-protect feature, which allows the users to protect the data from being accidentally overwritten. It is enabled when the write protect pin is driven high, which will disable the data write cycle. This can be used to prevent accidental programming of the memory.
Conclusion
AT24C08AN-10SI-2.5 is a reliable and robust memory device, which is suitable for embedded applications. Its Serial Peripheral Interface (SPI) Bus Specification ensures both high speed and secure data exchange. It is mainly used in embedded designs, real-time monitoring systems and automotive, industrial and medical environments. It has a very low power consumption, which is suitable for battery-powered systems, as well as its write-protect feature.
