FT24C64A-UTR-T

Overview

The FT24C64A-UTR-T is a 64Kbit (8K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features a write cycle time of 5 ms. The device operates within a supply voltage range of 1.8V to 5.5V and has an access time of 500 ns. It is housed in an 8-TSSOP package and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Non-volatile EEPROM memory architecture providing 64Kbit storage capacity
• Serial I²C bus interface for data communication
• Wide operating voltage range supporting 1.8V to 5.5V systems

Applications

• Data logging applications requiring non-volatile storage
• Configuration parameter storage in embedded systems
• Device identification and calibration data retention

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'UTR-T' matches the required 8-TSSOP packaging and tape-and-reel format. Check for RoHS compliance status and ensure the part meets environmental regulations for your target market. Validate that the obsolete status does not impact long-term supply chain stability for production needs.

Selection Notes

Select this component when a small-footprint serial EEPROM is required for low-power applications. The I²C interface simplifies PCB routing compared to parallel alternatives. Ensure the system voltage falls within the 1.8V to 5.5V range. Consider the 5ms write cycle time for application timing constraints. The 8-TSSOP package is suitable for surface-mount assembly processes.

Part Context

This part belongs to the FT24C64A series of serial EEPROMs from Fremont Micro Devices. The series offers various pin configurations and packages, including SOT-23-5, DFN, and TSSOP options. The FT24C64A-UTR-T specifically denotes the 8-pin TSSOP variant with tape-and-reel packaging, designed for automated surface-mount manufacturing.

Replacement Considerations

Public sources indicate this specific part number is obsolete. Verify availability of substitute parts such as FT24C64A-ENR-T or FT24C64A-USR-B from the same manufacturer, ensuring pin compatibility and electrical specifications match the original design requirements.
