24LC1026-I/ST

Memory IC Overview

The Microchip Technology 24LC1026-I/ST is a 1 Mbit (128K x 8) serial electrically erasable PROM. It operates within a voltage range of 2.5V to 5.5V and supports I2C compatible 2-Wire Serial Interface 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 SOIJ package and rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports both byte and page write operations with a 128-byte page buffer.
• Includes hardware write-protect functionality via the WP pin.
• Features Schmitt trigger inputs for enhanced noise suppression.

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Low-power electronic devices

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C). Confirm the 'ST' suffix indicates the 8-lead SOIJ package type. Ensure the specific part number matches the required voltage specifications for your system design.

Memory IC Selection Notes

Select this component when a 1 Mbit EEPROM with I2C interface is required. Consider the 2.5V minimum operating voltage constraint compared to other variants. Verify that the SOIJ package dimensions fit the target PCB layout constraints.

Memory IC Part Context

This device belongs to the 24XX1026 family, which includes the 24AA1026 and 24FC1026 models. These parts share similar architectural features but differ in operating voltage ranges and maximum clock frequencies. The 24LC1026 specifically targets applications requiring operation between 2.5V and 5.5V.

Memory IC Replacement Considerations

The 24AA1026 and 24FC1026 are functionally similar members of the same family. Substitution requires verification of voltage compatibility and clock speed requirements against the specific application needs.
