24LC04BT-E/SN

Memory IC Overview

The Microchip Technology 24LC04BT-E/SN 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 clock frequencies up to 400 kHz, with an access time of 900 ns. The device is housed in an 8-lead SOIC package and is rated for extended industrial temperatures from -40°C to +125°C.

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 lines for noise suppression
• Supports page write operations with a 16-byte buffer to enhance bus throughput
• Provides output slope control to eliminate ground bounce during switching

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage for embedded systems operating at 3.3V or 5V
• Parameter retention in consumer electronics utilizing standard I2C buses

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'SN' indicates the 8-lead SOIC package. Confirm RoHS compliance status as required by your manufacturing standards. Ensure the design accounts for the 2.5V minimum supply voltage requirement distinct from lower-voltage variants.

Memory IC Selection Notes

Select this component when operation above 2.5V is guaranteed and extended temperature performance is necessary. The 400 kHz speed is suitable for general-purpose I2C applications but may be insufficient for high-speed data acquisition compared to 1 MHz alternatives. Verify that the 8-lead SOIC footprint aligns with the target PCB layout constraints.

Memory IC Part Context

This part belongs to the 24LC04B family of 4-Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA04 and 24FC04 devices but is distinguished by its specific 2.5V minimum operating voltage and 400 kHz maximum clock frequency specifications.

Memory IC Replacement Considerations

The 24LC04BT-I/SN serves as a direct substitute if only industrial temperature ratings (-40°C to +85°C) are required. Other 4Kb I2C EEPROMs may require level shifting or voltage adjustment due to differing supply ranges.
