24LC1025-I/SM

Memory IC Overview

The Microchip Technology 24LC1025-I/SM is a 128K x 8 (1024K bit) Serial Electrically Erasable PROM. It operates within a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz. The device features a 2-wire I2C compatible interface, Schmitt trigger inputs for noise suppression, and hardware write-protect capability. It utilizes an 8-lead SOIJ package and functions across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial data transmission protocol with up to four devices on the same bus
• Includes hardware write-protect functionality via the WP pin to inhibit array writes
• Features output slope control to eliminate ground bounce during operation

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Advanced low-power electronic designs

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 power supply specifications. Ensure the I2C bus timing requirements are compatible with the master controller. Check for any factory programming options if custom initial memory states are necessary for the deployment.

Memory IC Selection Notes

Select this component when a 1 Mbit non-volatile storage solution is required with standard I2C connectivity. The Industrial temperature rating makes it suitable for general-purpose commercial and industrial environments. Consider the page write buffer size and endurance ratings against the expected write cycle frequency of the target application.

Memory IC Part Context

This part belongs to the 24XX1025 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA1025 and 24FC1025, which share similar architectural features but differ in voltage ranges and clock speeds. The 'I' designation indicates the industrial temperature range, while 'SM' specifies the surface mount SOIJ package.

Memory IC Replacement Considerations

Direct functional substitutes within the same family include the 24AA1025-I/SM and 24FC1025-I/SM. Verify voltage compatibility, as the 24AA1025 supports lower voltages down to 1.7V, while the 24FC1025 supports higher clock speeds. Ensure the replacement maintains the required 8-lead SOIJ package form factor.
