FT24C64A-UTR-B

Overview

The FT24C64A-UTR-B is a serial electrically erasable programmable read-only memory (EEPROM) integrated circuit manufactured by Fremont Micro Devices Ltd. This component provides a storage density of 64 kilobits, organized as 8192 words by 8 bits. It utilizes an I2C-compatible two-wire serial interface for data communication. The device operates within a supply voltage range of 1.7 volts to 5.5 volts and supports clock frequencies up to 1 megahertz. It is housed in a compact 5-pin ultra-small outline transistor (USON) surface-mount package.

Feature Summary

• Supports standard and high-speed modes on the I2C two-wire serial bus
• Provides non-volatile data retention without requiring power
• Features hardware write protection to prevent accidental data modification

Applications

• Consumer electronics configuration storage
• Industrial control system parameter logging
• Automotive sensor calibration data retention

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering code matches the exact USON-5 package variant required for your PCB footprint. Cross-reference the revision level with your design specifications to avoid potential interface timing discrepancies during integration.

Selection Notes

Select this component when a small form factor is critical due to its USON-5 packaging. It is suitable for designs requiring low power consumption and wide voltage operation. Consider it for applications needing reliable non-volatile storage for small datasets where I2C connectivity is already established on the system bus.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs from Fremont Micro Devices. The series offers various densities ranging from 1 kilobit to 1 megabit. The FT24C64A specifically targets mid-range storage needs. It shares functional similarities with other industry-standard I2C EEPROMs but is distinguished by its specific package and voltage characteristics.

Replacement Considerations

Compatible substitutes include the AT24C64N and M24C64W. Verify that replacement parts support the same 1.7V minimum operating voltage and USON-5 package dimensions. Confirm I2C address configurations match the target application requirements before substitution.
