24FC01T-E/ST

Memory IC Overview

The Microchip Technology 24FC01T-E/ST is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) utilizing a 2-Wire I2C compatible serial interface. It supports clock frequencies up to 1 MHz across a supply voltage range of 1.7V to 5.5V. The device features an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It operates within an extended temperature range of -40°C to +125°C and is housed in an 8-lead TSSOP package.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication with low standby current consumption
• Includes an 8-byte page write buffer for efficient data transfer operations
• Provides hardware write protection through the dedicated WP pin
• Features Schmitt trigger inputs and output slope control for signal integrity

Memory IC Applications

• Low-power embedded systems requiring non-volatile data storage
• Industrial applications operating in extended temperature environments
• Automotive electronic modules requiring AEC-Q100 qualified components
• Consumer devices needing compact surface-mount memory solutions

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'ST' specifies the 8-lead TSSOP package. Confirm the 'T' suffix indicates tape and reel packaging if required by automated assembly processes. Ensure compatibility with 1.7V to 5.5V supply rails and check for specific automotive qualification requirements if applicable.

Memory IC Selection Notes

Select this component when a 1 MHz I2C speed is necessary compared to slower 400 kHz alternatives. Choose the 24FC01 series over 24LC01B variants for operation at supply voltages below 2.5V. The 8-lead TSSOP package is suitable for space-constrained designs requiring surface mount technology. Verify that the hardware write protect feature meets system security requirements.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit EEPROMs from Microchip Technology. It shares functional similarities with the 24AA01 and 24LC01B but offers distinct electrical characteristics, specifically higher clock speeds and lower minimum operating voltages. The family utilizes a common I2C protocol and pinout structure across various package options.

Memory IC Replacement Considerations

Direct replacements include other 24FC01 variants with different packages such as 24FC01-E/SN or 24FC01-E/MS. Cross-family substitutes like the 24LC01B are limited to 400 kHz speeds and 2.5V minimum voltage. Ensure any replacement maintains the 1.7V to 5.5V operating range and 128x8 bit organization.
