FT24C64A-USR-T

Overview

The FT24C64A-USR-T is a 64Kbit (8K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I²C interface with a maximum clock frequency of 1 MHz, though some documentation cites 800 kHz. The device operates within a supply voltage range of 1.8V to 5.5V and offers an access time of 700 ns. It is housed in an 8-SOP package and supports a write cycle time of 5ms. The component functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Non-volatile storage architecture preserving data without power
• I²C serial interface for simplified system integration
• Wide operating voltage compatibility from 1.8V to 5.5V

Applications

• Data logging systems requiring persistent storage
• Configuration parameter retention in embedded controllers
• Calibration data storage for sensor modules

Procurement Notes

Verify the specific suffix against official Fremont Micro Devices documentation to confirm package type and electrical characteristics. Distributor listings may vary regarding clock frequency specifications. Ensure the ordering code matches the required SOP-8 form factor and voltage range before finalizing procurement orders.

Selection Notes

Select this component when a compact 64Kbit non-volatile memory solution is required for I²C-based designs. It is suitable for applications needing wide voltage operation and industrial temperature stability. Compare pinout compatibility with existing PCB layouts to ensure the SOP-8 package fits the designated footprint without modification.

Part Context

This part belongs to the FT24C64A series of serial EEPROMs from Fremont Micro Devices. The series provides various packaging options including DFN, TSSOP, and SOP variants. The USR-T designation specifically indicates the 8-SOP surface-mount package configuration within this product family.

Replacement Considerations

Compatible substitutes include FT24C64A-ENR-T (8-DFN) and FT24C64A-ESG-B (8-TSSOP). Verify pin-to-pin compatibility and package dimensions before substitution to ensure mechanical fit.
