24FC01T-I/OT

Memory IC Overview

The Microchip Technology 24FC01T-I/OT is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device supports page write operations with an 8-byte buffer and includes hardware write protection via the WP pin. It is housed in a 5-lead SOT-23 package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication for efficient data transfer
• Includes an 8-byte page write buffer to optimize write cycle performance
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Provides hardware write protection through the dedicated WP pin

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Automotive applications meeting AEC-Q100 qualification standards
• Embedded systems needing compact surface-mount memory solutions

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple form factors. Confirm the temperature grade corresponds to the intended operating environment. Ensure compatibility with the system's I2C bus voltage levels before integration. Check for any recent Product Change Notifications regarding packaging or material updates.

Memory IC Selection Notes

Select this component when a 1 MHz I2C interface is required alongside low-voltage operation down to 1.7V. The SOT-23-5 package offers a small footprint suitable for space-constrained designs. Consider the hardware write protect feature if data integrity against accidental writes is critical. Verify that the industrial temperature range meets the application's thermal requirements.

Memory IC Part Context

This device belongs to the 24XX01 family of 1 Kbit EEPROMs, which also includes the 24AA01 and 24LC01B variants. While sharing similar interfaces and capacities, the 24FC01 series is distinguished by its support for higher clock frequencies up to 1 MHz across the full voltage range. The 'T' suffix indicates tape and reel packaging, while 'I' denotes the industrial temperature grade.

Memory IC Replacement Considerations

Direct substitutes include other 24FC01 variants with different packages such as 24FC01-I/SN or 24FC01-I/MS. For lower speed requirements, the 24LC01B series may be considered, though it lacks 1 MHz support at voltages below 2.5V. The 24AA01 is functionally similar but limited to 400 kHz operation.
