Product details

1Kbit I2C EEPROM in a hand-solderable SOT-23-6

The Microchip 24C01CT-I/OT is a 1Kbit serial EEPROM with an I2C interface, organized as 128 bytes x 8 bits. The 900 ns access time is standard for this density and bus speed — fine for storing calibration constants, device IDs, or small lookup tables. The SOT-23-6 package is a six-pin footprint you can hand-solder without a hot-air station, which makes it a practical choice for prototype runs or low-volume production where reflow isn't available.

Supply voltage — 5V only, no 3.3V operation

This part is specified for 4.5V to 5.5V only. It will not operate at 3.3V. If your design runs on a 3.3V rail, the 24LC01BHT-I/MNY is a pin-compatible alternative that works down to 2.5V, though its write cycle time is 5 ms versus the 1 ms of this part.

Frequently asked questions

What is the memory size of 24C01CT-I/OT?

Design engineers need to confirm capacity for code storage or data logging.
