24LC1026T-I/SM

Memory IC Overview

The Microchip Technology 24LC1026T-I/SM is a 1-Mbit (128K x 8) serial EEPROM utilizing an I²C-compatible 2-Wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz, with a maximum active read current of 450 µA. The device features a 128-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead SOIJ package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to four devices on a single bus using configurable chip select pins A1 and A2.
• Includes hardware write protection that inhibits array writes when the WP pin is tied high.
• Features output slope control designed to eliminate ground bounce during operation.

Memory IC Applications

• Personal communications systems requiring non-volatile data storage
• Data acquisition applications needing low-power memory
• Embedded systems utilizing I²C bus architectures

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the 'SM' suffix corresponds to the 8-lead SOIJ package format. Cross-reference the full part number against the manufacturer's latest datasheet to confirm availability and any recent design changes.

Memory IC Selection Notes

Select this component for designs requiring 1-Mbit capacity with I²C connectivity. The 2.5V minimum supply voltage distinguishes it from lower-voltage variants like the 24AA1026. The SOIJ package offers a compact footprint suitable for space-constrained surface-mount assemblies. Consider the 128-byte page size when optimizing write throughput for your application.

Memory IC Part Context

This device belongs to the 24XX1026 family, which includes the 24AA1026 and 24FC1026 variants. These parts share identical functional specifications but differ in operating voltage ranges and maximum clock frequencies. The 24LC1026 specifically targets the 2.5V to 5.5V operational window.

Memory IC Replacement Considerations

The 24LC1026T-I/SN serves as a direct replacement if an SOIC-8 package is preferred over the SOIJ-8 form factor. Both variants maintain identical electrical characteristics and functionality within the specified industrial temperature range.
