24LC128T-E/MNY

Memory IC Overview

The Microchip Technology 24LC128T-E/MNY is a 16K x 8 (128 Kbit) Serial Electrically Erasable PROM (EEPROM). It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via an I2C compatible two-wire serial interface. The device features a page write time of 5 ms maximum, with a 64-byte page write buffer. It is housed in an 8-TDFN (2x3) package and is rated for an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using hardware address inputs A0, A1, and A2.
• Includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.
• Features hardware write-protect capability controlled by the WP pin to inhibit write operations.

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Advanced low-power electronic designs

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the Extended temperature grade (-40°C to +125°C) and the TDFN-8 surface mount package. Confirm compliance with RoHS directives and ensure the selected variant matches the required voltage and speed specifications for the target application environment.

Memory IC Selection Notes

Select this component when an extended industrial temperature range is required alongside standard I2C compatibility. Ensure the design accommodates the 2.5V minimum operating voltage. Consider the 64-byte page buffer size for write efficiency and verify that the physical footprint matches the 8-TDFN package dimensions available for this specific part number.

Memory IC Part Context

This device belongs to the 24XX128 family of 128K I2C Serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA128 and 24FC128, which differ primarily in operating voltage ranges and maximum clock frequencies. The 24LC128 series specifically targets applications requiring operation down to 2.5V.

Memory IC Replacement Considerations

Cross-reference with other 24LC128 variants sharing the same TDFN-8 package and Extended temperature rating. Verify functional equivalence regarding voltage limits and interface timing before substitution.
