24LC1025T-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC1025T-E/SN16KVAO is a 1-megabit (128K x 8) serial EEPROM utilizing an I²C-compatible interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. 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 SOIC package and rated for industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Supports cascading up to four devices on a single bus using configurable chip select pins A0 and A1.
• Includes hardware write protection that inhibits array writes when the WP pin is tied high.
• Features output slope control designed to eliminate ground bounce during operation.

Memory IC Applications

• Personal communications systems requiring non-volatile data storage
• Data acquisition applications needing low-power memory
• Industrial control systems operating across wide temperature ranges

Memory IC Procurement Notes

Verify the specific suffix '16KVAO' against official Microchip documentation to confirm it denotes a valid tape-and-reel packaging configuration or specific traceability code. Ensure the automotive temperature grade (-40°C to +125°C) matches the system requirements. Confirm RoHS compliance status with the manufacturer prior to final procurement.

Memory IC Selection Notes

Select this component for designs requiring 1Mbit capacity with I²C connectivity. The automotive temperature rating makes it suitable for harsh environments. Consider the 128-byte page write capability for efficient data logging. Verify that the system voltage remains above 2.5V to ensure proper operation at the specified 400 kHz speed.

Memory IC Part Context

This part belongs to the 24XX1025 family, which includes variants like the 24AA1025 and 24FC1025. While sharing the same core architecture and pinout, these variants differ in supply voltage ranges and maximum clock speeds. The 'E' designation indicates the extended industrial temperature range compared to the standard 'I' grade.

Memory IC Replacement Considerations

The 24LC1025T-I/SM is a compatible alternative offering the same functionality but limited to the standard industrial temperature range (-40°C to +85°C). Other family members such as the 24AA1025 support lower voltages but lack the extended temperature rating.
