24FC04T-E/Q4B

Memory IC Overview

The Microchip Technology 24FC04T-E/Q4B is a 4-kbit (512 x 8) serial EEPROM featuring an I2C interface with a maximum clock frequency of 1 MHz. It operates within a supply voltage range of 1.7 V to 5.5 V and supports SMD/SMT installation in an 8-UDFN package. The device ensures data retention for up to 200 years and functions across a temperature range from -40°C to +85°C, with a typical operating current of 5 µA.

Memory IC Feature Summary

• Supports high-speed I2C communication at frequencies up to 1 MHz
• Operates on a wide supply voltage range from 1.7 V to 5.5 V
• Provides long-term non-volatile data retention capabilities

Memory IC Applications

• Data storage in industrial control systems
• Configuration memory in consumer electronics
• Parameter logging in automotive instrumentation

Memory IC Procurement Notes

Verify the specific suffix 'E' against official Microchip documentation to confirm the extended temperature grade (-40°C to +125°C), as standard 'I' variants typically cover -40°C to +85°C. Confirm the 8-UDFN package availability and ensure the ordering code matches the exact pinout and marking requirements for your PCB design before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact 4-kbit EEPROM is required for I2C-based architectures. The 8-UDFN package offers space efficiency for dense layouts. Ensure the system voltage remains within the 1.7 V to 5.5 V range. Consider the 'E' grade if operation beyond +85°C is necessary, as it may support higher thermal limits compared to standard industrial grades.

Memory IC Part Context

This part belongs to the Microchip 24FCxx series of serial EEPROMs, designed for low-power, high-reliability data storage applications. The series utilizes standard I2C protocols for compatibility with various microcontrollers. The 'T' indicates tape-and-reel packaging, while 'Q4B' specifies the 8-UDFN footprint and lead-free composition.

Memory IC Replacement Considerations

Direct substitutes include the 24FC04T-I/Q4B for standard industrial temperature ranges or the 24AA04T-E/UOT for alternative packaging. Verify pin compatibility and software register alignment when migrating between different EEPROM families within the same manufacturer portfolio.
