FT24C64A-USG-T

Overview

The FT24C64A-USG-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 at 5V operation. The device supports a supply voltage range of 1.8V to 5.5V and features a write cycle time of 5ms maximum. Access time is specified at 550 ns. It operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-SOP package.

Feature Summary

• Supports standard two-wire bi-directional serial interface for data access
• Includes hardware write protect pin for data security
• Features automatic erase before write capability
• Designed for low voltage and low power consumption applications

Applications

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

Procurement Notes

Verify the manufacturer designation as Fremont Micro Devices Ltd or equivalent authorized entity. Confirm the specific suffix USG-T corresponds to the 8-SOP tape and reel packaging. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a 64Kbit capacity is required with I²C connectivity. The wide voltage range allows integration into both 1.8V and 5V logic systems. The industrial temperature rating makes it suitable for harsh environments. Consider the 8-SOP package dimensions for PCB layout constraints.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs from Fremont Micro Devices. It shares architectural similarities with other members like the FT24C256A and FT24C16A, differing primarily in storage density. The series is characterized by CMOS technology for low power operation and standard I²C compatibility.

Replacement Considerations

Compatible substitutes include the STMicroelectronics M24C64-WMN6P and Microchip 24LC64T-I/SN. Verify pinout compatibility and voltage levels before substitution. Ensure the replacement package matches the 8-SOP footprint.
