24LC04BT-I/MC

Memory IC Overview

The Microchip Technology 24LC04BT-I/MC is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I²C serial interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes a 16-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead MSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I²C protocols.
• Includes hardware write protection to inhibit memory writes when the WP pin is tied high.
• Features output slope control to minimize ground bounce during switching operations.
• Provides high ESD protection exceeding 4,000V on all pins.

Memory IC Applications

• Non-volatile data storage in consumer electronics
• Configuration parameter retention in embedded systems
• Device identification and calibration data logging

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and Industrial temperature grade as required by the design. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the system's voltage and interface requirements exactly.

Memory IC Selection Notes

Select this component for applications requiring low-power non-volatile storage with simple serial connectivity. The 400 kHz clock speed suits moderate data throughput needs. Consider the MSOP package dimensions for space-constrained PCB layouts. Verify that the 2.5V minimum operating voltage aligns with the target system's power rails.

Memory IC Part Context

This part belongs to the 24XX04 family of 4-Kbit EEPROMs from Microchip Technology. It shares functional similarities with the 24AA04 and 24FC04 but differs in operating voltage and maximum clock frequency specifications. The family utilizes a common pinout and protocol, facilitating design flexibility across different voltage and speed requirements.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04B variants with different packages such as SOIC or PDIP, provided the interface and voltage specs match. Cross-family replacements like 24AA04 require verification of lower voltage support. Always confirm pin compatibility and electrical characteristics before substitution.

Memory IC FAQ

How does the hardware write-protect feature function?

Connecting the WP pin to VCC inhibits all write operations to the memory array, while connecting it to VSS enables normal read and write access.

What is the maximum page write size for this device?

The device supports a page write buffer of up to 16 bytes, allowing multiple bytes to be written in a single transaction without intermediate acknowledgments.
