24LC025-E/MS

Memory IC Overview

The Microchip Technology 24LC025-E/MS is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and features an I²C-compatible 2-wire serial interface with clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, ensuring typical standby current of 1 μA and active read current of 1 mA. It supports page write operations with a 16-byte buffer and includes hardware noise suppression via Schmitt trigger inputs.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard 2-wire I²C compatible serial bus protocol.
• Features a 16-byte page write buffer for efficient sequential data storage operations.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Provides high reliability with over one million erase/write cycles and more than 200 years of data retention.

Memory IC Applications

• Data acquisition systems requiring non-volatile parameter storage
• Personal communication devices needing compact memory solutions
• Industrial control applications utilizing I²C bus architectures

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates automotive temperature range (-40°C to +125°C) and 'MS' denotes the MSOP-8 package. Confirm that the 24LC025 variant lacks the hardware write-protect pin found in the 24LC024 counterpart. Ensure compatibility with the required supply voltage range of 2.5V to 5.5V for your system design.

Memory IC Selection Notes

Select this component when an I²C interface is required for small capacity non-volatile storage. The 24LC025 differs from the 24LC024 by omitting the hardware write-protect pin. Choose the 'E' grade for extended industrial or automotive temperature environments compared to the standard 'I' grade. Verify that the system does not require the lower 1.7V operating voltage supported by the 24AA series.

Memory IC Part Context

This part belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial EEPROMs. These devices share identical pinouts and functional protocols but differ in voltage ranges and write-protection features. The 24LC025 specifically targets applications requiring operation above 2.5V without hardware write protection, distinguishing it from the protected 24LC024 and the wider voltage 24AA025.

Memory IC FAQ

Does the 24LC025 support hardware write protection?

No, the WP pin is not internally connected on the 24LC025. Hardware write protection is only available on the 24LC024 variant within this family.

How many devices can be connected on the same bus?

Up to eight 24LC025 devices can be connected to the same bus using different combinations of the A0, A1, and A2 address pins.
