24CW1280T-I/OT

Memory IC Overview

The Microchip Technology 24CW1280T-I/OT is a non-volatile EEPROM memory IC with a storage capacity of 128Kb, organized as 16K x 8. It features an I2C serial interface supporting a maximum clock frequency of 1 MHz and has a typical 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 surface-mount SOT-23-5 package.

Memory IC Feature Summary

• Supports software-based write protection mechanisms to prevent accidental data modification.
• Operates across a wide supply voltage range suitable for low-power applications.
• Features high data retention capabilities for long-term non-volatile storage.

Memory IC Applications

• Industrial control systems requiring reliable parameter storage
• Consumer electronics needing configuration data retention
• Automotive modules utilizing industrial-grade temperature components

Memory IC Procurement Notes

Verify the exact suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels between 1.6V and 5.5V. Confirm I2C address settings if multiple devices are used on the same bus. Check for RoHS compliance status in current datasheets.

Memory IC Selection Notes

Select this component when a compact SOT-23-5 footprint is required for 128Kb I2C EEPROM storage. It is suitable for designs needing industrial temperature stability and software write protection. Compare against the 24CS128 series if higher speed (3.4 MHz) is necessary instead of the standard 1 MHz operation found in the 24CW series.

Memory IC Part Context

This part belongs to the 24CW1280 series of serial EEPROMs manufactured by Microchip Technology. The series is designed for general-purpose data storage in embedded systems. The 'I' indicates an industrial temperature range, while '/OT' specifies the SOT-23-5 surface mount package variant.

Memory IC Replacement Considerations

Direct pin-compatible replacements include other 24CW1280 variants with different packages such as 24CW1280T-I/MUY or 24CW1280T-I/ST. For higher speed requirements, consider the 24CS128 series, though electrical characteristics differ.
