24LC024T-E/SN

Memory IC Overview

The Microchip Technology 24LC024T-E/SN is a 2 Kbit (256 x 8) Serial Electrically Erasable PROM featuring an I²C-compatible 2-Wire serial interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz with a maximum access time of 900 ns. The device utilizes low-power CMOS technology, offering typical standby current of 1 μA and active read current of 1 mA. It includes hardware write protection via the WP pin, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Features a 16-byte page write buffer that allows efficient data transfer by storing multiple bytes before initiating an internal self-timed write cycle.
• Includes hardware write-protect functionality accessible via the WP pin to prevent accidental modification of the memory array when enabled.
• Supports cascading up to eight devices on the same bus using three hardware address pins (A0, A1, A2) for expanded contiguous memory addressing.

Memory IC Applications

• Data logging applications requiring non-volatile storage of sensor readings or system parameters.
• Configuration storage in embedded systems where user-defined settings must be retained during power loss.
• Calibration data retention for industrial instrumentation and measurement devices.

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the Automotive temperature grade (-40°C to +125°C) rather than the standard Industrial grade. Confirm the 'SN' designation corresponds to the 8-lead SOIC package type. Ensure the 'T' prefix matches the required tape and reel packaging format for automated assembly processes. Cross-reference the datasheet revision to confirm compatibility with your system's electrical requirements.

Memory IC Selection Notes

Select this component when an I²C interface is required for low-pin-count memory expansion. The Automotive grade ensures reliability under wider thermal conditions compared to Industrial variants. Consider the 16-byte page buffer size for optimizing write throughput in software drivers. Verify that the 2.5V minimum operating voltage aligns with the system's power rail capabilities.

Memory IC Part Context

This part belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2Kb Serial EEPROMs. It shares functional similarities with the 24LC025 but differs in organization and write-protect availability. The 24LC024 series specifically provides hardware write protection, distinguishing it from the unprotected 24LC025 variant within the same product line.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC024-I/SN and 24LC024-E/MC. Verify package compatibility and temperature range specifications when substituting.
