24CW320-I/SN

Memory IC Overview

The Microchip Technology 24CW320-I/SN is a 32 Kbit I2C Serial EEPROM housed in an 8-SOIC package. It features a maximum clock frequency of 1 MHz and an access time of 450 ns. The device operates within a supply voltage range of 1.6 V to 5.5 V and supports industrial temperature conditions from -40°C to +85°C. It includes software write protection capabilities.

Memory IC Feature Summary

• Supports high-speed I2C communication with a maximum clock frequency of 1 MHz.
• Includes software write protection to prevent accidental data modification.
• Operates across a wide supply voltage range suitable for various logic levels.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics needing configuration parameter retention
• Automotive modules operating under industrial temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'I/SN' confirms the Industrial temperature grade (-40°C to +85°C) and SOIC-8 package. Ensure compatibility with the system's I2C bus speed, as this part supports up to 1 MHz. Confirm that the required software write protection mechanism aligns with the application's security requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 32 Kbit capacity is required alongside high-speed 1 MHz I2C performance. It is suitable for designs needing operation down to 1.6 V. Compare against the 24LC32AT series if lower cost or different packaging is preferred, noting that the CW series offers higher speed and broader voltage support.

Memory IC Part Context

This part belongs to the 24CW320 family of serial EEPROMs designed for applications demanding fast access times and flexible power supply options. It shares architectural similarities with other 24-series devices but distinguishes itself through its 1 MHz clock capability and specific industrial temperature rating.

Memory IC Replacement Considerations

The 24CW320T-I/Q4B is a compatible alternative offering identical electrical specifications but utilizes a UDFN-8 package instead of SOIC-8. Verify footprint compatibility before substitution.
