24LC025/SN

Memory IC Overview

The Microchip Technology 24LC025/SN is a 2 Kbit (256 x 8) Serial Electrically Erasable PROM featuring a 2-wire I²C compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes a 16-byte page write buffer, Schmitt trigger inputs for noise suppression, and hardware write protection capabilities are absent on this specific model. It offers over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication with I²C compatibility
• Includes a 16-byte page write buffer for efficient data storage operations
• Features Schmitt trigger inputs and output slope control for enhanced noise immunity
• Provides hardware write protection functionality via the WP pin

Memory IC Applications

• Low-power consumer electronics requiring non-volatile data storage
• Industrial systems utilizing I²C bus architectures
• Personal communication devices needing compact memory solutions
• Data acquisition systems requiring reliable parameter retention

Memory IC Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 package configuration required for your design. Confirm that the Industrial temperature grade (-40°C to +85°C) meets your operational environment specifications. Ensure the absence of internal hardware write protection on the 24LC025 variant aligns with your security requirements, as this differs from the 24LC024 model.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM capacity is sufficient for application needs. Choose the 24LC025/SN specifically for its surface-mount SOIC-8 packaging format. Consider this part for designs operating within the 2.5V to 5.5V voltage range. Verify that the lack of hardware write protection on the 24LC025 does not compromise system integrity compared to protected variants.

Memory IC Part Context

This component belongs to the Microchip 24AA024/24LC024/24AA025/24LC025 family of serial EEPROMs. It shares architectural similarities with the 24LC024 but lacks the hardware write-protect pin found in the 24XX024 series. The device utilizes CMOS technology for low power consumption and is designed for high-density applications within standard 8-pin packages.

Memory IC Replacement Considerations

The 24LC024/SN serves as a direct functional substitute if hardware write protection is required. The 24AA025/SN offers similar performance with an extended voltage range starting at 1.7V. Cross-reference package dimensions and pinouts when substituting to ensure mechanical compatibility.
