24FC01-I/SN

Memory IC Overview

The Microchip Technology 24FC01-I/SN is a 1 Kbit Electrically Erasable PROM (EEPROM) organized as one block of 128 x 8-bit memory. It features a 2-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 1 MHz at supply voltages between 1.7 V and 5.5 V. The device operates within an industrial temperature range of -40°C to +85°C and utilizes an 8-lead SOIC package.

Memory IC Feature Summary

• Supports bidirectional data transmission via a 2-wire serial bus protocol.
• Includes hardware write protection controlled by the WP pin state.
• Features Schmitt trigger inputs for noise suppression on SCL and SDA lines.
• Provides page write capability with an 8-byte internal buffer.

Memory IC Applications

• Non-volatile data storage in low-power embedded systems
• Configuration parameter retention in industrial controllers
• Device identification and calibration data logging

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm voltage compatibility with the target system, as the device supports operation down to 1.7V. Ensure the design accounts for the specific I2C pull-up requirements and timing constraints defined in the electrical characteristics section of the datasheet.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient for application needs. The Industrial temperature grade (-40°C to +85°C) suits general commercial and industrial environments. Consider the 8-lead SOIC package for standard surface-mount assembly processes. Verify that the host controller supports the required I2C clock speeds and addressing scheme.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA01 and 24LC01B but offers higher speed compatibility up to 1 MHz compared to the 400 kHz limit of its counterparts. The family provides various package options including SOIC, TSSOP, and MSOP.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24FC01 series such as 24FC01-E/SN for extended temperature ranges or different packages like 24FC01-I/ST. Cross-family replacements like 24AA01 or 24LC01B are available but operate at lower maximum clock frequencies.
