24FC04T-E/ST

Memory IC Overview

The Microchip Technology 24FC04T-E/ST is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire serial interface compatible with I²C. It supports clock frequencies up to 1 MHz and operates on a single supply voltage ranging from 1.7V to 5.5V. The device utilizes low-power CMOS technology, offering maximum active read current of 1 mA and standby current of 3 µA at extended temperatures. It includes a 16-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. The component is qualified for automotive applications under AEC-Q100 standards and provides data retention exceeding 200 years.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication across the full operating voltage range
• Includes a 16-byte page write buffer to optimize sequential data writing operations
• Features hardware write protection controlled by the dedicated WP pin
• Provides enhanced ESD protection exceeding 4,000V and latch-up resistance

Memory IC Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Industrial control devices needing extended temperature operation
• Consumer electronics utilizing low-voltage power supplies
• Data logging modules requiring non-volatile storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the 'E' designation corresponds to the Extended temperature range (-40°C to +125°C). Ensure the 'T' suffix indicates tape and reel packaging if automated assembly is intended. Cross-reference the manufacturer part number against official datasheets to validate electrical characteristics before integration.

Memory IC Selection Notes

Select this component when an I²C EEPROM requires 1 MHz bus speeds at voltages below 2.5V. It is suitable for designs demanding extended industrial or automotive temperature ranges. Consider the 16-byte page buffer for efficient data throughput. Verify that the 8-pin TSSOP package fits the available board space and that the hardware write-protect feature aligns with system security requirements.

Memory IC Part Context

This device belongs to the 24XX04 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA04 and 24LC04B but distinguishes itself through support for 1 MHz clock frequencies and operation down to 1.7V. The family offers various package options including SOIC, MSOP, and TSSOP, catering to diverse PCB layout constraints while maintaining standard I²C protocol compatibility.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24FC04 in alternative packages such as SOIC or MSOP. For lower speed requirements, the 24LC04B may be considered if the voltage range permits. The 24AA04 serves as a functional equivalent but is limited to 400 kHz operation at voltages below 2.5V.
