Disadvantages: - Limited memory size may not be suitable for applications requiring larger storage capacity - Serial interface may limit data transfer speed compared to parallel interfaces

Working Principles

The 93AA56BT-I/MNY EEPROM utilizes a floating gate transistor structure to store digital information. When a write operation is performed, an electric charge is trapped in the floating gate, altering the transistor's threshold voltage. This change allows the stored data to be read back accurately even when power is removed. The serial interface enables easy communication with microcontrollers or other devices.
