FT25C64A-UTR-B

Overview

The FT25C64A-UTR-B is a 64Kbit (8K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an SPI interface with a maximum clock frequency of 20 MHz and features a write cycle time of 5ms. The device operates within a supply voltage range of 1.8V to 5.5V and supports access times of 500 ns. It is housed in an 8-TSSOP package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed SPI communication for efficient data transfer
• Provides non-volatile storage with long-term data retention capabilities
• Operates on a wide single-supply voltage range for flexible integration

Applications

• Data logging systems requiring persistent storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation

Procurement Notes

Verify the specific suffix 'UTR-B' against official Fremont Micro Devices documentation to confirm the exact package type, tape-and-reel quantity, and environmental compliance status. Ensure the design accounts for the 20 MHz SPI clock limit and 5.5V maximum supply voltage during system validation.

Selection Notes

Select this component when high-speed SPI access is required compared to standard I2C alternatives. Consider the 8-TSSOP footprint constraints and the 1.8V to 5.5V operating range. Verify that the 64Kbit capacity meets the application's data storage needs without excessive overhead.

Part Context

This part belongs to the FT25C series of serial EEPROMs from Fremont Micro Devices. It offers higher speed performance than the I2C-based FT24C series, making it suitable for applications demanding faster read/write cycles while maintaining non-volatile data integrity in compact surface-mount packages.
