Advantages and Disadvantages

Advantages

• Non-volatile storage ensures data retention even during power loss.
• Electrically erasable memory allows for easy reprogramming.
• Low power consumption prolongs battery life in portable devices.
• Compact package size facilitates integration into various electronic systems.
• High reliability ensures long-term data integrity.

Disadvantages

• Limited memory capacity (1 kilobit) may not be sufficient for certain applications requiring larger storage.
• Slower write cycle time compared to some other EEPROM chips.
• Restricted address space due to a single address bit (A0).

Working Principles

AT24C01A-10PI-2.5 utilizes an electrically controlled floating gate to store and retrieve data. When a byte is written, an electrical charge is trapped in the floating gate, representing a logical "1" or "0". This charge can be erased by applying a higher voltage, allowing the byte to be rewritten.

The chip communicates with the host device using a serial interface, consisting of the SDA and SCL lines. The host initiates read or write operations by sending appropriate commands and addresses to the chip.
