24LC025-E/MC

Memory IC Overview

The Microchip Technology 24LC025-E/MC is a 2 Kbit (256 x 8) serial EEPROM utilizing an I2C-compatible 2-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features a 16-byte page write buffer, self-timed erase/write cycles, and hardware write protection capabilities. It supports up to eight devices on the same bus via functional address lines A0, A1, and A2. The component is housed in an 8-lead DFN package and is rated for an industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional data transfer using a standard 2-wire serial interface compatible with I2C protocols.
• Includes a 16-byte page write buffer to optimize data writing efficiency across memory blocks.
• Features Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce.
• Provides high reliability with over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Applications

• Data acquisition systems requiring non-volatile storage for sensor calibration values.
• Personal communication devices needing low-power configuration memory.
• Industrial controllers storing operational parameters and system settings.
• Embedded systems managing device identification and configuration tables.

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the Automotive grade (-E) and DFN package (-MC). Confirm the voltage range requirement aligns with the 2.5V minimum specification for the LC series. Ensure the design accounts for the absence of a hardware write-protect pin on the 24LC025 variant compared to the 24LC024.

Memory IC Selection Notes

Select this part when an I2C interface is required for small-scale non-volatile storage in automotive or industrial environments. The 24LC025 differs from the 24LC024 by lacking a hardware write-protect pin. Verify that the application voltage stays above 2.5V; if lower voltages are needed, consider the 24AA025 series instead.

Memory IC Part Context

This component belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial Electrically Erasable PROMs. The family shares common architecture but varies in voltage ranges and write-protection features. The 24LC025 specifically targets applications requiring operation between 2.5V and 5.5V without hardware write protection.

Memory IC Replacement Considerations

Public confirmed substitutes include the 24LC024-E/MC, which offers identical specifications except for the inclusion of a hardware write-protect pin. Other variants within the same package and temperature grade may be considered if interface compatibility is maintained.
