24LC04BT/ST

Memory IC Overview

The Microchip Technology 24LC04BT/ST is a 4-Kbit (512 x 8) serial EEPROM featuring an I²C-compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz, with a maximum access time of 900 ns. The device utilizes an 8-lead TSSOP package and is rated for industrial temperatures from -40°C to +85°C. Key electrical characteristics include a standby current of 5 µA maximum and an operating current of 3 mA maximum.

Memory IC Feature Summary

• Supports page write operations with a 16-byte buffer to enhance bus throughput efficiency.
• Includes hardware write protection via the WP pin to inhibit memory writes when tied to VCC.
• Features Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control devices needing parameter retention
• Consumer electronics utilizing low-power memory solutions

Memory IC Procurement Notes

Verify that the ordering suffix 'ST' corresponds specifically to the TSSOP package type as defined in the manufacturer's documentation. Confirm the temperature grade 'I' aligns with the required -40°C to +85°C operational range for your specific application environment before finalizing procurement.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is sufficient for the application requirements. Ensure the system voltage remains above 2.5V to maintain the specified 400 kHz clock frequency. Consider the TSSOP package dimensions if board space is constrained compared to SOIC or MSOP alternatives.

Memory IC Part Context

This part belongs to the 24LC04B series of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA04 and 24FC04 models but differs in minimum operating voltage and maximum clock speed specifications. The series is designed for applications requiring reliable, low-power data retention.

Memory IC Replacement Considerations

The 24LC04BT/SN serves as a direct package alternative using the SOIC format. Other compatible parts within the same family include the 24LC04BT-I/MS for MSOP packaging. Verify voltage and speed compatibility when substituting with 24AA04 or 24FC04 variants.

Memory IC FAQ

How does the hardware write protect function operate?

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

What is the maximum page write size for this device?

The device features a 16-byte page write buffer, allowing up to 16 bytes to be written in a single sequence without generating a Stop condition.
