24LC1025T-I/SN

Memory IC Overview

The Microchip Technology 24LC1025T-I/SN is a 128K x 8 (1024K bit) Serial Electrically Erasable PROM. It operates within a voltage range of 2.5V to 5.5V and supports I2C™ compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device features a 128-byte page write buffer, hardware write-protect capability, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to four devices on the same data bus using configurable chip select inputs.
• Includes a 128-byte page write buffer to optimize sequential data writing operations.
• Features hardware write protection via the WP pin to inhibit array writes when tied high.

Memory IC Applications

• Personal communications systems requiring non-volatile data storage
• Data acquisition applications needing low-power memory solutions
• Industrial control systems utilizing I2C communication protocols

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage operating range aligns with system requirements, as the LC variant differs from AA or FC versions. Ensure the source documentation corresponds to the exact part number to validate electrical characteristics and interface compatibility before integration.

Memory IC Selection Notes

Select this component for designs requiring 1Mbit capacity with standard I2C connectivity. The Industrial temperature rating suits general-purpose electronics. Verify power supply stability within the 2.5V to 5.5V window. Consider the 400 kHz maximum clock speed for bandwidth constraints. Evaluate physical space requirements against the 8-lead SOIC footprint.

Memory IC Part Context

This device belongs to the 24XX1025 family, which includes variants like the 24AA1025 and 24FC1025. These parts share identical functional architectures but differ in voltage ranges and clock speeds. The LC series specifically targets the 2.5V to 5.5V operational spectrum, distinguishing it from lower voltage or higher frequency counterparts within the same product line.

Memory IC Replacement Considerations

Direct substitutes include the 24AA1025T-I/SN and 24FC1025T-I/SN. Verify voltage compatibility, as the AA version supports 1.7V while the FC version supports 1 MHz clocks. Ensure the replacement maintains the same 8-lead SOIC package and industrial temperature rating for mechanical and environmental fit.
