The AT24C01AY1-10YU-1.8-T is a memory device specifically designed for use in a wide range of electronic applications. It is manufactured by Atmel Corporation and is a low-cost, low-power CMOS serial EEPROM with a guaranteed accuracy on its write operations. The device is available in 8 pin DIP package and includes an 8 MHz internal oscillator.

Application Field

The AT24C01AY1-10YU-1.8-T is typically used in data acquisition, data processing, and communication systems due to its ability to store multiple bytes of data. It can also be used in embedded systems, such as automotive and industrial systems, for storing non-volatile configuration data. Since the device includes an 8 MHz internal oscillator, it can be used to set up communication systems in the 2.4 or 5 GHz bands. The device is ideal for storing and processing data intensive tasks such as real-time clock functions.

Working Principle

The AT24C01AY1-10YU-1.8-T memory device is based on a serial EEPROM architecture. The device has an 8-bit data bus which is connected to an on-chip register. The register provides storage for up to 8 bytes of data. The data byte can be read out of the device by a simple instruction. The instructions used to access the device can be sent from the processor via the serial interface.

The device can store data for up to 10 years and is guaranteed to perform up to ±10mA write and read accuracy over the full temperature range. The device includes an internal write and read protection mechanism to ensure that data is not corrupted during data write, erase, and read cycles. The device also includes hardware reset, write protect, and write enable lines for added protection and control.

The memory device can be operated in both sequential and random access modes. Sequential access refers to accessing the data bytes stored in the device one after another and random access refers to accessing any particular data byte in the device. Both the modes of operation can be performed with 0–8 MHz clock rate.

The device also includes an 8MHz internal oscillator which is used to clock the bus when communicating with other devices. In addition, it includes an internal low voltage reset (LVR) circuit which monitors the supply voltage level and can generate a reset signal if the supply voltage falls below the trip point of the LVR.

Conclusion

The AT24C01AY1-10YU-1.8-T is an ultra-low-power CMOS serial EEPROM memory device designed for use in a wide range of electronic applications. It offers a guaranteed accuracy on write operations and can store data for up to 10 years. The device features an 8-bit data bus and is capable of operating in both sequential and random access modes. It also includes an 8 MHz internal oscillator and a low voltage reset (LVR) circuit. The device thus makes an ideal choice a variety of embedded applications.
