24FC02T-E/Q4B

Memory IC Overview

The Microchip Technology 24FC02T-E/Q4B is a 2-kbit (256 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It features an I2C interface with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports industrial temperature conditions from -40°C to +85°C. It utilizes an 8-pin UDFN package and offers a data retention period of 200 years.

Memory IC Feature Summary

• Supports standard I2C two-wire serial communication protocol
• Operates across a wide voltage range suitable for low-power applications
• Provides long-term non-volatile data storage capabilities

Memory IC Applications

• Industrial control systems requiring reliable parameter storage
• Consumer electronics needing configuration data retention
• Automotive modules operating in industrial temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates extended temperature or commercial grade variants against official datasheets, as suffixes define operational ranges. Confirm the 'Q4B' packaging designation matches required reel specifications. Ensure compatibility with system voltage levels between 1.7 V and 5.5 V before integration.

Memory IC Selection Notes

Select this component when a compact 2-kbit memory solution is required for I2C-based architectures. The UDFN-8 package suits space-constrained designs. Verify that the 1 MHz clock speed meets system timing requirements and that the industrial temperature rating aligns with environmental conditions.

Memory IC Part Context

This part belongs to Microchip's 24FC series of I2C EEPROMs. It shares the same physical footprint and interface protocols as other capacities in the family, such as the 24CS256T-I/Q4B, facilitating potential design scalability while maintaining pin compatibility across different memory sizes.

Memory IC Replacement Considerations

Direct substitutes include other 2-kbit I2C EEPROMs from Microchip like the 24FC02T-I/Q4B, noting the temperature grade difference. Cross-vendor replacements require verification of I2C address bits and voltage thresholds.
