Technology Introduction

AT24C08D-UUM1B-T, which stands for “Serial EEPROM”, is a type of non-volatile memory chip used to store persistent data. This memory device is manufactured using advanced CMOS technology and is designed to be compact yet highly reliable. AT24C08D is part of a family of Serial EEPROMs designed and manufactured by Atmel Corporation.

Application Field

AT24C08D is widely used in many fields, including automotive, consumer electronics, industrial and medical applications. It is commonly used for applications such as non-volatile versions of RAM and ROM, to store logging or configuration data, to log usage data for life cycle tracking, to store consumer information such as radio and television settings, and to extend the flash memory of a device.

Working Principle

AT24C08D utilizes two pins for data communication along with additional pins for a logic level interface. The two data communication pins are CK and DI (Clock and Data Input). This allows the device to be interfaced with any microcontroller or other logic levels. Once the *CS (Chip Select) pin is activated, a start condition is created by sending a low voltage to the CS pin. Once the start condition is treated, data packets can be sent and received by setting and reading the CK (clock) and DI (Data Input) pins. After each bit of data is sent, the clock pin is set high and then low again to reset the level, allowing the next bit to be sent. When the data is finished being sent, the CS pin is set high, ending the communication session.

Conclusion

In conclusion, AT24C08D-UUM1B-T is a popular serial memory device capable of storing non-volatile data. The device is versatile and is used in many applications from automotive and medical, to consumer electronics. AT24C08D has two data communication pins and since it is logic level applicable, it is compatible with all microcontrollers, making this device a popular choice for many applications.
