24CW320T-I/SN

Memory IC Overview

The Microchip Technology 24CW320T-I/SN is a serial electrically erasable programmable read-only memory (EEPROM) device featuring a storage capacity of 32 kbit. It utilizes an I2C interface with a maximum clock frequency of 1 MHz and offers a memory organization of 4 k x 8. The component operates within a supply voltage range of 1.6 V to 5.5 V and supports surface mount installation in an SOIC-8 package. It provides a data retention period of 200 years and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports software write protection for enhanced data security
• Operates on a single power supply ranging from 1.6 V to 5.5 V
• Features high endurance and long-term data retention capabilities

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage operation
• Embedded systems needing secure parameter storage

Memory IC Procurement Notes

Verify the specific suffix 'SN' confirms the SOIC-8 package type, as the provided reference data primarily lists UDFN-8 variants for this model number. Ensure the industrial temperature grade (-40°C to +85°C) matches the application requirements. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 32 kbit EEPROM with I2C communication is required in a standard 8-pin surface-mount package. It is suitable for designs operating between 1.6 V and 5.5 V where software write protection is necessary. Compare against UDFN-8 variants if space constraints differ, ensuring the pinout compatibility aligns with the PCB layout design.

Memory IC Part Context

This part belongs to the 24CW320 series of serial EEPROMs manufactured by Microchip Technology. The series is characterized by its I2C interface and software write protection features. While other variants like the 24CW320T-I/MUY utilize a UDFN-8 package, the SN suffix indicates a distinct physical footprint, typically corresponding to the SOIC-8 form factor within this product family.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for the 24CW320T-I/SN are not available in the provided source material. Verify package compatibility when considering cross-references, as the 24CW320 series includes UDFN-8 variants which may require adapter solutions or redesign.
