24CW1280T-I/ST

Memory IC Overview

The Microchip Technology 24CW1280T-I/ST is a 128Kb (16K x 8) serial EEPROM featuring 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 includes software write protection and functions across an industrial temperature range of -40°C to +85°C. Packaged in an 8-TSSOP format, it utilizes a 5 ms word/page write cycle time for non-volatile data retention.

Memory IC Feature Summary

• Supports I2C two-wire serial communication with high-speed mode capability up to 1 MHz.
• Includes software-based write protection mechanisms to prevent accidental data modification.
• Designed for industrial temperature environments ranging from -40°C to +85°C.

Memory IC Applications

• Camera module data storage
• Industrial control systems
• Consumer electronics requiring non-volatile configuration storage

Memory IC Procurement Notes

Verify the specific suffix 'T/I/ST' against official Microchip documentation to confirm tape-and-reel packaging and industrial temperature grade. Ensure compatibility with system voltage levels between 1.6V and 5.5V. Cross-reference datasheet revisions dated August 2025 for any pinout or electrical characteristic updates before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 128Kb capacity is required with I2C connectivity and robust industrial temperature tolerance. Compare against the 24LC128 series if lower speed or different voltage ranges are acceptable. Verify that the 8-TSSOP package fits the PCB footprint constraints and that the 1 MHz clock rate meets the system's bus timing requirements.

Memory IC Part Context

This part belongs to the Microchip 24CW series of serial EEPROMs, which are optimized for camera modules and general-purpose data storage. The series offers various capacities and packaging options, providing designers with flexible solutions for non-volatile memory applications requiring reliable data retention and standard serial interfaces.

Memory IC Replacement Considerations

The 24CW1280-I/ST is a parameter-equivalent alternative available in tube packaging instead of tape-and-reel. Both parts share identical electrical characteristics and pinouts, allowing for direct substitution if packaging differences do not impact assembly processes.
