24CW320T-I/MUY

Memory IC Overview

The Microchip Technology 24CW320T-I/MUY is a 32 Kbit (4 k x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes a 2-Wire I2C interface with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 1.6 V to 5.5 V and features an access time of 450 ns. It is housed in an UDFN-8 surface-mount package and supports industrial operating temperatures from -40°C to +85°C. The component offers 200-year data retention and includes software write protection capabilities.

Memory IC Feature Summary

• Supports standard I2C communication protocol with up to 1 MHz clock speed
• Includes software-based write protection mechanisms for data security
• Operates across a wide voltage range from 1.6 V to 5.5 V
• Designed for industrial temperature environments

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded systems needing compact surface-mount memory solutions
• Automotive infotainment and instrumentation modules

Memory IC Procurement Notes

Verify the specific suffix MUY confirms the UDFN-8 package type and reel packaging configuration. Ensure the I designation matches the required industrial temperature range of -40°C to +85°C for your application environment. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 32 Kbit capacity is required alongside a small UDFN-8 footprint. It is suitable for designs operating below 3.3 V due to its 1.6 V minimum supply voltage. Choose this part over higher-speed variants if cost or power consumption is prioritized over the 1 MHz interface limit. Verify that the I2C address pins are configured correctly for the target system bus topology.

Memory IC Part Context

This EEPROM belongs to the 24CW series, which focuses on low-voltage operation and software write protection. The 24CW320 variant specifically provides 32 Kbit density. The MUY suffix denotes the UDFN-8 package style, distinguishing it from other pinout configurations like TSSOP or SOIC found in related family members.

Memory IC Replacement Considerations

Check for 24LC320 or 24AA320 equivalents if voltage levels differ. Verify pin compatibility for direct replacement in existing layouts.
