24FC1026-I/SN

Memory IC Overview

The Microchip Technology 24FC1026-I/SN is a 128K x 8 (1024 Kbit) serial electrically erasable PROM. It operates across a voltage range of 1.8V to 5.5V with a maximum clock frequency of 1 MHz at VCC ≥ 2.5V. The device features a 2-wire I2C compatible interface, Schmitt trigger inputs for noise suppression, and output slope control. It supports up to 128-byte page writes, hardware write protection via the WP pin, and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation within specified voltage ranges
• Includes hardware write-protect capability through the dedicated WP pin
• Features Schmitt trigger inputs and output slope control for signal integrity

Memory IC Applications

• Personal communications systems requiring non-volatile storage
• Data acquisition applications needing reliable parameter retention
• Embedded controllers utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific voltage operating range aligns with system requirements, as FC variants support lower minimum voltages than LC counterparts. Ensure compatibility with existing I2C bus protocols before integration.

Memory IC Selection Notes

Select this component when high-speed 1 MHz communication is necessary alongside low standby power consumption. It is suitable for designs requiring hardware-level write protection and robust noise immunity in industrial environments. Compare against AA and LC series variants based on specific voltage and speed constraints.

Memory IC Part Context

This part belongs to the 24XX1026 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA1026 and 24LC1026 but offers enhanced clock speeds. The 'I' designation indicates an industrial temperature range, while 'SN' specifies the 8-lead SOIC package format.

Memory IC Replacement Considerations

The 24LC1026-I/SN serves as a functional substitute if reduced clock speed is acceptable. Verify voltage thresholds carefully, as the 24LC1026 requires a minimum of 2.5V compared to the 1.8V minimum of the 24FC1026.
