Working Principle

AT49BV001-90TI utilizes a standard floating gate technology for both reading and writing operations. To store information, a voltage is applied to a cell to dope the charge carriers into the dielectric layer between the control and floating gate layers, which is then programmed.

To read data, the integrated circuit is programmed and the data is retrieved by applying a voltage across the cell and measuring the current flowing through the cell. This current value is then compared to a reference voltage and depends on the amount of charge stored on the floating gate.

The cell can be erased by applying a negative voltage across the charge, and the data is then re-programmed anew. This device also employs an internal ECC algorithm that can correct up to eight bits in a one 256-bit word.

Conclusion

AT49BV001-90TI is an advanced EEPROM integrated circuit from Atmel Corporation that is designed for applications requiring large memory space and high reliability. AT49BV001-90TI can be used for a variety of applications including industrial control, motor control, communications, and car navigation systems, among other applications.
