24CW1280T-I/CS1668

Memory IC Overview

The Microchip Technology 24CW1280T-I/CS1668 is a 128-kbit (16K x 8) serial EEPROM utilizing an I2C interface. It operates within a supply voltage range of 1.6V to 5.5V and supports clock frequencies up to 1 MHz with a typical access time of 450 ns. The device features software write protection and is housed in a 4-CSP package. It is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I2C communication with 1 MHz clock frequency
• Includes software-based write protection mechanisms
• Operates across a wide voltage range from 1.6V to 5.5V

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded devices needing configuration parameter retention
• Consumer electronics with limited pin count constraints

Memory IC Procurement Notes

Verify the specific suffix against official documentation, as 'CS1668' may indicate a specific tape-and-reel or packaging variant distinct from standard commercial listings. Confirm RoHS compliance status and ensure the selected package matches PCB footprint requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact 4-pin CSP package is required for space-constrained designs. It is suitable for applications demanding reliable data retention without external write-protect hardware pins, provided software-level protection meets system security requirements.

Memory IC Part Context

This part belongs to the 24CW series of serial EEPROMs from Microchip Technology. The series offers various capacities and packages, sharing common I2C interface characteristics but differing in physical dimensions and specific operational parameters based on the chosen suffix.

Memory IC Replacement Considerations

Direct substitutes include other 128-kbit I2C EEPROMs in similar small packages, such as the 24CW1280T-I/ST or 24FC128 variants, though pinout compatibility and voltage ranges must be verified.
