24FC04T-E/MUY

Memory IC Overview

The Microchip Technology 24FC04T-E/MUY is a 4-Kbit Electrically Erasable PROM (EEPROM) organized as two blocks of 256 x 8-bit memory. It features a Two-Wire Serial Interface compatible with I²C protocols, supporting maximum clock frequencies up to 1 MHz when VCC is between 1.7V and 5.5V. The device operates within an extended temperature range of -40°C to +125°C and utilizes Low-Power CMOS technology.

Memory IC Feature Summary

• Supports bidirectional data transmission via a standard Two-Wire Serial Interface compatible with I²C protocols.
• Includes hardware write-protect functionality controlled by the WP pin to inhibit write operations across the entire memory array.
• Features Schmitt Trigger inputs and filter circuits on SCL and SDA lines to suppress noise spikes and ensure reliable operation in noisy environments.

Memory IC Applications

• Data logging applications requiring non-volatile storage for sensor readings or system parameters.
• Configuration storage for embedded systems needing persistent settings across power cycles.
• Device identification and calibration data retention in industrial control modules.

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the UDFN package type and Extended temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability codes matching the component marking requirements.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I²C communication is required alongside low-voltage operation down to 1.7V. Choose the Extended temperature variant for environments exceeding standard industrial limits. Consider the UDFN package for space-constrained surface-mount designs requiring compact footprints.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs, which includes variants like the 24AA04 and 24LC04B. While sharing similar interface protocols and memory architectures, the 24FC04 series is distinguished by its support for higher clock speeds and lower minimum operating voltages compared to other family members.

Memory IC Replacement Considerations

Direct substitutes within the same package and electrical specifications include the 24FC04T-I/MUY for industrial temperature ranges. Other compatible packages from the 24FC04 family such as 24FC04T-E/OT or 24FC04T-E/ST may serve as alternatives if form factor differences are acceptable.
