24CW1280T-I/MUY

Memory IC Overview

The Microchip Technology 24CW1280T-I/MUY is a 128 Kbit (16K x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes an I2C (Two-Wire) serial interface with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 1.6V to 5.5V and supports an industrial temperature range from -40°C to +85°C. It features software write protection, page write capabilities, and a typical access time of 450 ns. The component is housed in an 8-UDFN package.

Memory IC Feature Summary

• Supports high-speed I2C communication with a 1 MHz clock rate
• Includes software-based write protection mechanisms
• Operates across a wide industrial temperature range
• Provides non-volatile data retention

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics for configuration data retention
• Automotive modules needing reliable low-voltage memory
• IoT devices utilizing space-efficient UDFN packaging

Memory IC Procurement Notes

Verify the specific suffix 'MUY' corresponds to the 8-UDFN package and tape-and-reel shipping format. Confirm that the 'I' designation matches the required -40°C to +85°C industrial operating temperature range for your application environment. Ensure compatibility with the 1.6V to 5.5V supply voltage constraints during system design validation.

Memory IC Selection Notes

Select this part when a 128 Kbit capacity is required alongside a compact 8-UDFN footprint. It is suitable for designs needing I2C connectivity without external level shifters if voltages align. Consider the 1 MHz speed limit against higher-speed alternatives like the 24CS series if faster throughput is critical. Verify power supply stability within the specified 1.6V to 5.5V window.

Memory IC Part Context

This component belongs to the Microchip 24CW series of serial EEPROMs. It shares architectural similarities with other members like the 24CW640 and 24CW2560, differing primarily in storage density. The 'T' indicates tape and reel packaging, while 'I' denotes industrial temperature rating. It complements the broader 24LC and 24FC families by offering optimized performance for I2C interfaces.

Memory IC Replacement Considerations

The 24CW1280T-I/ST serves as a pin-compatible alternative using an 8-TSSOP package instead of UDFN. Other densities in the same series, such as 24CW640T-I/MUY or 24CW2560T-I/MUY, share identical interfaces and packages but differ in capacity.
