24FC1025T-I/SM

Memory IC Overview

The Microchip Technology 24FC1025T-I/SM is a 1-Mbit (128K x 8) serial EEPROM utilizing I²C-compatible 2-wire communication. It operates within a voltage range of 1.8V to 5.5V and supports clock frequencies up to 1 MHz. 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 functions across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication with low-power CMOS technology
• Includes a 128-byte page write buffer for efficient data transfer
• Features hardware write protection and Schmitt trigger inputs for signal integrity

Memory IC Applications

• Personal communications devices requiring non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Embedded controllers managing configuration settings

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 the system design, as the FC variant supports lower voltages than LC or AA counterparts. Ensure the manufacturer part number corresponds exactly to the intended specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I²C access is required alongside low power consumption. It is suitable for applications demanding extensive endurance and long-term data retention. Consider the 128-byte page buffer size for optimizing write throughput in memory-intensive designs compared to smaller page sizes.

Memory IC Part Context

This device belongs to the 24XX1025 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA1025 and 24LC1025 but offers enhanced speed capabilities. The family provides scalable memory solutions for various embedded applications requiring robust non-volatile data storage.

Memory IC Replacement Considerations

The 24LC1025T-I/SM serves as a compatible alternative, though it operates at a maximum clock frequency of 400 kHz. Verify that the reduced speed meets application timing requirements before substituting.
