FT24C64A-USR-B

Overview

The FT24C64A-USR-B is a non-volatile EEPROM memory integrated circuit manufactured by Fremont Micro Devices Ltd. It provides a storage capacity of 64Kb, organized as 8K words by 8 bits. The device utilizes an I2C serial interface with a maximum clock frequency of 1 MHz and features a typical access time of 500 ns. It operates within a supply voltage range of 1.8V to 5.5V and supports a write cycle time of 5 ms for both word and page operations. The component is housed in an 8-MSOP surface-mount package and is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed I2C communication with a maximum clock frequency of 1 MHz
• Provides reliable non-volatile data retention without requiring power
• Operates across a wide supply voltage range from 1.8V to 5.5V
• Designed for robust performance in industrial environments

Applications

• Data logging systems requiring persistent storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules
• Device identification and serial number storage

Procurement Notes

Verify the specific suffix 'USR-B' against official Fremont Micro Devices documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with system voltage levels and I2C bus timing requirements before integration. Confirm RoHS3 compliance status through current manufacturer declarations.

Selection Notes

Select this component when a 64Kb EEPROM with I2C interface is required in an 8-pin MSOP package. Consider the 1.8V to 5.5V operating range for flexibility in low-power or standard logic designs. Verify that the 500 ns access time meets the system's read speed requirements and that the 85°C max temperature rating suits the application environment.
