FT24C04A-KNR-T

Overview

The FT24C04A-KNR-T is a 4Kbit (512 x 8) non-volatile EEPROM manufactured by Fremont Micro Devices Ltd. It features an I²C serial interface with a maximum clock frequency of 1 MHz and an access time of 550 ns. The device operates within a supply voltage range of 1.8V to 5.5V and supports page write cycles of 5 ms. It is housed in an 8-UFDFN package with an exposed pad, suitable for surface mount applications across a temperature range of -40°C to 85°C.

Feature Summary

• Supports standard I²C serial communication protocol
• Provides non-volatile data retention without power
• Operates across wide voltage and temperature ranges

Applications

• Consumer electronics data storage
• Industrial control system configuration memory
• Automotive embedded systems logging

Procurement Notes

Verify the specific suffix 'KNR' corresponds to the 8-UFDFN package variant during procurement. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering code matches the exact pinout and thermal pad requirements for your PCB layout design before finalizing purchase orders.

Selection Notes

Select this component when a compact 4Kbit EEPROM solution is required for space-constrained designs. It is appropriate for applications needing reliable non-volatile storage with low power consumption. Consider the I²C interface compatibility with the host microcontroller and verify that the operating voltage aligns with the system's power rails.

Part Context
