FT24C64A-UMR-B

Overview

The FT24C64A-UMR-B is a 64-Kbit serial I2C bus EEPROM manufactured by Fremont Micro Devices. It is organized as 8K x 8 bits and housed in an 8-pin MSOP package. The device supports standard I2C protocol with a maximum clock frequency of 1 MHz. It operates within a supply voltage range of 1.7V to 5.5V and functions across an industrial temperature range of -40°C to +85°C. Key electrical characteristics include high-speed page write capabilities and robust data retention specifications.

Feature Summary

• Supports standard I2C bus communication protocol for efficient data transfer
• Provides hardware write protection to prevent accidental data modification
• Offers configurable device addressing to allow multiple devices on the same bus
• Ensures long-term data retention suitable for industrial applications

Applications

• Consumer electronics requiring non-volatile memory storage
• Industrial control systems needing reliable parameter storage
• Automotive modules utilizing low-voltage memory components

Procurement Notes

Verify the specific suffix 'UMR-B' against the manufacturer's official datasheet to confirm the exact package type, tape-and-reel quantity, and temperature grade. Ensure the ordering code matches the required I2C address configuration and voltage specifications for your target application before finalizing procurement.

Selection Notes

Select this component when a compact 8-pin surface-mount solution is required for 64-Kbit storage. It is suitable for designs needing I2C compatibility with support for both 1.7V and 5V logic levels. Consider its physical dimensions and thermal performance relative to other MSOP packages in your PCB layout constraints.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs from Fremont Micro Devices. These devices are designed to replace legacy parallel EEPROMs with simpler serial interfaces. The series typically includes variants with different capacities such as 24C02, 24C04, 24C08, 24C16, 24C32, and 24C64, sharing similar interface protocols and pinouts.

Replacement Considerations

Compatible alternatives include the AT24C64 or M24C64 from other manufacturers. Verify that substitute parts match the 8-pin MSOP footprint, I2C address bits, and operating voltage ranges. Check for any differences in page size or write cycle endurance if migrating between brands.
