FT25C08A-UTR-B

Overview

The FT25C08A-UTR-B is an 8Kb (1024 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a high-speed SPI interface with a maximum clock frequency of 20 MHz and features a supply voltage range of 1.8V to 5.5V. The device operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-TSSOP package.

Feature Summary

• Supports high-speed SPI communication for efficient data transfer
• Provides non-volatile storage with hardware write protection capabilities

Applications

• Data logging systems requiring persistent storage
• Configuration memory in embedded controllers
• Calibration data retention in sensor modules

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required package type and operating temperature range for the target application environment.

Selection Notes

Select this component when a small footprint and high-speed serial access are required. Compare against I2C alternatives if pin count is constrained, noting that SPI typically offers faster throughput. Confirm voltage levels match the system logic to ensure reliable operation across the specified temperature range.

Part Context

This part belongs to the FT25C series of serial EEPROMs from Fremont Micro Devices. It is distinct from the FT24C series, which uses I2C interfaces. The FT25C series is designed for applications demanding rapid read/write cycles and robust data retention in compact electronic devices.
