24LC04BT/SN

Memory IC Overview

The Microchip Technology 24LC04BT/SN is a 4-Kbit (512 x 8) serial EEPROM utilizing 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. The device features a maximum access time of 900 ns and a page write cycle time of 5 ms. It is housed in an 8-lead SOIC package and functions across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard two-wire serial bus protocol
• Includes hardware write protection controlled by the WP pin state
• Features Schmitt trigger inputs for noise suppression on SDA and SCL lines
• Contains a 16-byte page write buffer for efficient sequential data storage

Memory IC Applications

• Embedded systems requiring non-volatile parameter storage
• Industrial control devices needing configuration retention
• Consumer electronics with low-power memory requirements

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package type. Confirm RoHS compliance status and ensure the component meets the intended operating voltage specifications. Check for any automotive qualification requirements if applicable to the target application environment.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is sufficient for the application's data storage needs. Ensure the system design accommodates the 2.5V minimum supply voltage requirement. Verify that the I²C bus speed does not exceed 400 kHz under the specified operating conditions.

Memory IC Part Context

This part belongs to the 24LC04B family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA04 and 24FC04, differing primarily in supply voltage ranges and maximum clock frequencies. The device is designed for general-purpose data storage in embedded environments.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24LC04B series such as 24LC04BT-I/MS or 24LC04BT-E/SN, provided the package and temperature ratings match the design requirements.
