24FC01T-I/SN

Memory IC Overview

The Microchip Technology 24FC01T-I/SN 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 writes up to 8 bytes and includes hardware write protection via the WP pin. It is housed in an 8-lead SOIC 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 operations
• Features Schmitt trigger inputs and output slope control for noise suppression
• Provides hardware write protection through the dedicated WP pin

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage in embedded controllers
• Parameter retention in low-voltage electronic devices

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'SN' indicates the 8-lead SOIC package. Confirm RoHS compliance status as specified in the manufacturer's documentation. Ensure the application circuit supports the 1.7V to 5.5V operating voltage range and utilizes appropriate pull-up resistors for the I2C bus lines.

Memory IC Selection Notes

Select this component when a 1 Kbit non-volatile memory solution is required with I2C connectivity. It is suitable for applications needing operation down to 1.7V, distinguishing it from variants restricted to higher minimum voltages. Consider the 8-lead SOIC package for surface mount assembly requirements and verify that the 1 MHz clock speed meets system timing constraints.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA01 and 24LC01B but offers enhanced performance with support for 1 MHz clock frequencies compared to the 400 kHz limit of other family members. The device maintains compatibility with standard I2C protocols while providing robust data retention characteristics.

Memory IC Replacement Considerations

Direct substitutes include the 24AA01 and 24LC01B, though these operate at lower maximum clock frequencies of 400 kHz. Verify voltage thresholds, as the 24LC01B requires a minimum of 2.5V. Other package options within the same electrical specification are available under different ordering suffixes.
