24FC16T-E/Q4B

Memory IC Overview

The Microchip Technology 24FC16T-E/Q4B is a 16-kbit (2048 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It utilizes 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 surface-mount installation in an 8-UDFN package. It features a data retention period of 200 years and functions across a temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication for efficient data transfer.
• Operates over a wide supply voltage range from 1.7 V to 5.5 V.
• Provides extended industrial temperature operation up to +125°C.
• Ensures long-term data integrity with a 200-year retention capability.

Memory IC Applications

• Industrial control systems requiring reliable non-volatile storage
• Consumer electronics utilizing low-voltage power supplies
• Automotive embedded applications demanding high-temperature stability

Memory IC Procurement Notes

Verify the specific suffix 'E' against official documentation, as standard listings often reference the 'I' variant. Confirm the exact operating temperature range (+125°C vs +85°C) matches project requirements. Ensure the 8-UDFN package dimensions align with PCB layout constraints. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with similar capacity devices.

Memory IC Selection Notes

Select this component when a 16-kbit EEPROM is required with extended temperature capabilities up to +125°C. The 1 MHz I2C speed suits applications needing faster access than standard 400 kHz devices. Verify that the 1.7 V minimum voltage meets system power rails. Consider the 8-UDFN footprint for compact designs. Compare against the 'I' grade if extreme temperature performance is not necessary.

Memory IC Part Context

This device belongs to the Microchip 24FCxx series of serial EEPROMs. These components are designed for general-purpose data storage using the I2C protocol. The series offers various capacities and packaging options. The 24FC16T-E/Q4B specifically targets applications requiring robustness in harsh environments due to its extended temperature rating.

Memory IC Replacement Considerations

The 24FC16T-I/Q4B serves as a common alternative but typically has a lower maximum operating temperature of +85°C. Verify if the extended temperature rating is critical before substituting. Other family members like the 24FC32 or 24FC64 offer higher capacities but may require software adjustments.
