24CW1280T-I/CS0668

Memory IC Overview

The Microchip Technology 24CW1280T-I/CS0668 is a non-volatile EEPROM memory IC with a storage capacity of 128 Kbit, organized as 16K x 8. It features an I2C serial interface supporting clock frequencies up to 1 MHz and has an access time of 450 ns. The device operates within a supply voltage range of 1.6V to 5.5V and is rated for industrial temperatures from -40°C to +85°C. It is housed in a compact 4-CSP package.

Memory IC Feature Summary

• Supports software write protection for data security
• Operates on a single power supply ranging from 1.6V to 5.5V
• Features high-speed I2C serial communication interface

Memory IC Applications

• Industrial control systems requiring reliable data logging
• Consumer electronics needing configuration storage
• Automotive modules utilizing I2C peripherals

Memory IC Procurement Notes

Verify the specific suffix CS0668 against the official datasheet to confirm the 4-CSP package type and tape-and-reel packaging format. Ensure the industrial temperature grade (-40°C to +85°C) matches the operational environment requirements. Confirm RoHS3 compliance status prior to final procurement decisions.

Memory IC Selection Notes

Select this component when a small footprint is required alongside standard I2C compatibility. The 1.6V minimum operating voltage allows integration with low-power logic families. Verify that the 1 MHz clock speed meets system timing constraints compared to slower legacy EEPROM alternatives.

Memory IC Part Context

This part belongs to the 24CW series of serial EEPROMs designed for cost-sensitive applications. It shares functional similarities with other members like the 24CW640 but offers higher density. The series is characterized by its robust write endurance and long-term data retention capabilities suitable for general-purpose memory tasks.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes within the same 24CW family, such as different capacity variants in the same package. Verify if older revisions or alternative manufacturers offer equivalent electrical characteristics without modifying the PCB layout.
