Here’s a detailed rundown of the part you asked about, 24LC64T‑I/SN from Microchip Technology. If you like, I can pull up the full datasheet PDF as well and/or show pin-out and application notes.

• It is a 64 Kbit serial EEPROM organised as 8 K × 8 bits.

• It uses a 2-wire serial (I²C™) interface.

• Supply voltage range: 2.5 V to 5.5 V for this “LC” version. 

• Maximum clock frequency: 400 kHz for the I²C interface (when supply ≥2.5 V). 

• Operating temperature (Industrial “I” suffix): –40 °C to +85 °C. 

• Package: 8-pin SOIC (surface mount). 

• Page-write capability: up to 32 bytes per write cycle. 

• Data retention: > 200 years (typical specification). 

• Endurance: > 1 million erase/write cycles. 

Since it’s an 8-pin SOIC, typical pin-outs are:

Make sure the address pins (A0, A1, A2) are tied to a valid logic level (0 or Vcc) depending on your bus configuration.

• Non-volatile storage of calibration data, configuration parameters, logs etc. in microcontroller systems.

• Anywhere you need small-capacity memory with I²C interface (e.g., many embedded systems, IoT devices, consumer electronics).

• Because of its industrial temp range, it’s suitable for moderately harsh environments as well (–40 °C to +85 °C).

• Voltage compatibility: Ensure your system’s I²C bus and Vcc fall within 2.5–5.5 V. If you need lower than 2.5 V, then another variant (e.g., “AA” version) is required. 

• Bus addressing: The device allows up to 8 devices on the same bus (via the A0–A2 pins). So if you plan multiple EEPROMs, you can differentiate them. 

• Write cycles & timing: Page write time typical ~5 ms. Don’t attempt to read/write too frequently without considering this. It’s self-timed internally. 

• Write protection: Use the WP pin if you need to prevent accidental writes to the entire array or part of it.
