24LC04BT-E/MS

Memory IC Overview

The Microchip Technology 24LC04BT-E/MS is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I²C compatible serial interface. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz. The device utilizes an 8-lead MSOP package and is rated for extended temperature operation from -40°C to +125°C. Key electrical characteristics include a maximum access time of 900 ns, a page write time of 5 ms, and standby current of 5 µA.

Memory IC Feature Summary

• Features hardware write protection via the WP pin to inhibit memory writes when tied to VCC.
• Includes Schmitt trigger inputs and filter circuits on SCL and SDA pins for noise suppression.
• Supports acknowledge polling to determine internal write cycle completion.

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control devices operating in extended temperature environments
• Consumer electronics utilizing low-power I²C communication

Memory IC Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature grade (-40°C to +125°C) and 'MS' indicates the MSOP-8 package. Confirm RoHS compliance status as per the manufacturer's latest documentation. Ensure the design accounts for the 2.5V minimum supply voltage requirement distinct from lower voltage variants.

Memory IC Selection Notes

Select this component for applications requiring reliable non-volatile storage with I²C connectivity. The extended temperature rating makes it suitable for harsh environments. Consider the 16-byte page write buffer for efficient data writing. Verify that the system voltage remains above 2.5V to ensure proper operation at the specified 400 kHz clock speed.

Memory IC Part Context

This part belongs to the 24LC04B series of 4-Kbit serial EEPROMs manufactured by Microchip Technology. The series offers various package options including SOIC, PDIP, and TDFN. The 'BT' designation typically refers to the tape and reel packaging format, while 'E' specifies the extended temperature range variant within the product family.

Memory IC Replacement Considerations

Direct substitutes within the same family include 24LC04BT-I/MS for industrial temperature ranges or 24LC04BH-E/MS for alternative package configurations. Cross-family replacements like 24AA04 or 24FC04 require verification of voltage compatibility and clock speed limitations.
