Memory is an important type of hardware used in many computing devices. One example of a memory device is the AT24C04AN-10SC-2.5. It is a 4 Kbyte Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device. This device features a low-voltage, low pin count sector write locking architecture which can significantly reduce code complexity and system cost for a given data retention requirement.

Application Field

AT24C04AN-10SC-2.5 is used in many applications such as storing system parameters, user preferences, hardware identification numbers, and other data which needs to be kept even when power is lost. This device can also be used in systems which require non-volatile storage of data which can be modified or reconfigured in the field.

The AT24C04AN-10SC-2.5 can be used in embedded systems, Consumer Electronics, Automotive, Medical Applications, Industrial Control, Security and Identification, Building Automation, and a variety of other applications where data needs to be stored in a non-volatile manner.

Working Principle

The AT24C04AN-10SC-2.5 is an electrical device, so its working principle involves the flow of electrons in a circuit. This device consists of an array of cells connected on an address bus, data bus, and control bus. Each cell holds a bit, either a 0 or a 1, which represents data stored in the device.

When the device is powered on, the data stored in each cell is read out serially and placed in an internal register. This data can then be accessed or written by the processor, using control signals and the address and data buses. The processor can write new data to the cells, which is then retained even when power is removed.

The AT24C04AN-10SC-2.5 device also has a sector write locking feature which allows certain sections of the memory array to be locked. This prevents unwanted tampering with data stored in these locked cells, as they can no longer be overwritten.

Conclusion

The AT24C04AN-10SC-2.5 is an excellent choice for applications which require the retention of data even after the power is removed. Its sector write locking feature adds an extra layer of security to the stored data. This device is used in many applications such as embedded systems, consumer electronics, automotive, medical applications, industrial control, security and identification systems, and building automation.
