24LC025T-E/MS

Memory IC Overview

The Microchip Technology 24LC025T-E/MS is a 2 Kbit (256 x 8) serial electrically erasable PROM. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I²C compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, featuring typical standby current of 1 μA and active read current of 1 mA. It offers hardware write protection capabilities, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce. The component ensures data retention exceeding 200 years and endurance of over one million erase/write cycles.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using hardware address pins A0, A1, and A2.
• Includes Schmitt trigger inputs and filter circuits to suppress noise spikes on the SCL and SDA lines.
• Features an internal VCC threshold detector that disables erase/write logic if power drops below nominal levels.
• Provides a 16-byte page write buffer to optimize data transfer efficiency.

Memory IC Applications

• Data logging in industrial environments requiring non-volatile storage
• Configuration memory for embedded systems operating at high temperatures
• Parameter storage in automotive electronic modules

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 '/MS' designation corresponds to the MSOP-8 package type. Ensure the source documentation explicitly lists this exact part number variant within the 24LC025 family specifications before procurement.

Memory IC Selection Notes

Select this component when application requirements demand operation across an extended temperature range up to 125°C. The MSOP-8 package is suitable for space-constrained surface-mount designs. Note that unlike the 24LC024, this 2Kb variant does not feature a dedicated hardware Write-Protect pin; write protection must be managed via software or external circuitry.

Memory IC Part Context

This component belongs to the Microchip 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial EEPROMs. The 'LC' prefix denotes a 2.5V minimum operating voltage, distinguishing it from the 'AA' series which supports lower voltages down to 1.7V. The 'E' suffix specifies the Automotive temperature qualification, while 'I' would indicate the Industrial range.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: 24LC025-I/MS, 24LC025-E/MC, 24LC025-I/SN.
