24LC32AT-I/SN

The 24LC32AT-I/SN is a 32 Kbit (4 K x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM) device manufactured by Microchip Technology. This component is designed for applications requiring non-volatile memory storage, allowing data to be retained even when power is removed.

Key Features:

1. Memory Organization: The 24LC32AT-I/SN is organized as 4,096 words of 8 bits each, providing a total storage capacity of 32 Kbits. This organization allows for efficient data management and retrieval.

2. Interface: The device communicates via a 2-wire I²C (Inter-Integrated Circuit) interface, which simplifies connections and reduces the number of required pins. The I²C protocol supports multiple devices on the same bus, making it ideal for applications with multiple memory components.

3. Operating Voltage: The EEPROM operates within a voltage range of 1.7V to 5.5V, making it suitable for low-power applications. This flexibility allows it to be used in battery-operated devices.

4. Data Retention and Endurance: The 24LC32AT-I/SN boasts a data retention period of over 100 years and can endure up to 1,000,000 write cycles per memory cell. This durability ensures long-term reliability for critical data storage.

5. Write Protection: The device features a hardware write protection mechanism, which can be enabled to prevent accidental overwriting of data. This is particularly useful in applications where data integrity is paramount.

6. Speed: The EEPROM supports fast data transfer rates, with a maximum clock frequency of 1 MHz in standard mode and up to 400 kHz in fast mode. This allows for quick read and write operations, enhancing overall system performance.

7. Package Options: The 24LC32AT-I/SN is available in various package types, including 8-lead PDIP (Plastic Dual In-line Package), SOIC (Small Outline Integrated Circuit), and TSSOP (Thin Shrink Small Outline Package). This variety allows designers to choose the most suitable form factor for their specific application.

8. Temperature Range: The device is rated for operation over a wide temperature range, typically from -40°C to +85°C, making it suitable for industrial and automotive applications.
