24FC1026-I/SM

Memory IC Overview

The Microchip Technology 24FC1026-I/SM is a 128K x 8 (1024 Kbit) serial EEPROM utilizing I²C-compatible 2-wire interface. It operates within a voltage range of 1.8V to 5.5V and supports clock frequencies up to 1 MHz at VCC ≥ 2.5V, or 400 kHz at lower voltages. The device features a 128-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. It provides over one million erase/write cycles with data retention exceeding 200 years. Available in an 8-lead SOIJ package, it functions across industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation for efficient data transfer
• Includes 128-byte page write buffer to optimize write performance
• Features hardware write-protect functionality to secure memory arrays
• Incorporates Schmitt trigger inputs for enhanced noise immunity

Memory IC Applications

• Personal communication devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Embedded controllers managing configuration settings
• Industrial equipment storing calibration data

Memory IC Procurement Notes

Verify that the ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the '/SM' suffix corresponds to the 8-lead Small Outline Integrated Circuit (SOIJ) package variant. Ensure the specific part number matches the required voltage and speed specifications for your application design.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I²C communication is required alongside standard EEPROM reliability. It is suitable for designs operating between 1.8V and 5.5V where hardware write protection is necessary. Consider the 128-byte page size for write efficiency compared to byte-write-only alternatives.

Memory IC Part Context

This device belongs to the 24XX1026 family, which includes variants like 24AA1026 and 24LC1026. The 'FC' designation specifically indicates support for 1 MHz clock speeds, distinguishing it from the 400 kHz limited AA and LC versions. All family members share identical pinouts and functional protocols.

Memory IC Replacement Considerations

Direct substitutes include 24AA1026-I/SM and 24LC1026-E/SM. Note that these alternatives are limited to 400 kHz maximum clock frequencies. Verify if the system timing requirements can accommodate the reduced speed before substituting.
