24FC01T-E/OT

Memory IC Overview

The Microchip Technology 24FC01T-E/OT is a 1 Kbit (128 x 8) serial EEPROM featuring an I2C interface with a maximum clock frequency of 1 MHz. It operates on a single supply voltage ranging from 1.7 V to 5.5 V and is housed in a 5-lead SOT-23 package. The device supports extended temperature operation from -40°C to +125°C and meets AEC-Q100 automotive qualification standards.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication for efficient data transfer
• Includes hardware write protection via the WP pin to secure memory content
• Features Schmitt trigger inputs and output slope control for noise suppression
• Provides over one million erase/write cycles with more than 200 years of data retention

Memory IC Applications

• Automotive electronic systems requiring AEC-Q100 qualified components
• Industrial equipment operating in extended temperature environments
• Consumer electronics utilizing low-voltage power supplies
• Embedded systems needing non-volatile storage for configuration data

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm the device meets AEC-Q100 requirements if used in automotive applications. Ensure the I2C bus pull-up resistors are selected appropriately for the 1 MHz clock speed and supply voltage range to maintain signal integrity.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C communication is necessary compared to standard 400 kHz devices. Choose the SOT-23-5 package for compact surface-mount designs. Ensure the application voltage remains within the 1.7 V to 5.5 V range and requires extended temperature capability up to +125°C for reliable operation.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs, which also includes the 24AA01 and 24LC01B variants. The 24FC01 distinguishes itself by supporting higher clock frequencies up to 1 MHz across its full voltage range, whereas other family members may be limited to lower speeds at reduced voltages.

Memory IC Replacement Considerations

Direct functional replacements within the same package include the 24FC01T-E/OT36KVAO. Other family members like the 24AA01 or 24LC01B offer similar memory capacity but may have different electrical characteristics regarding maximum clock frequency and minimum operating voltage.
