FT25C16A-UTR-B

Overview

The FT25C16A-UTR-B is a 16Kbit (2K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an SPI interface with a maximum clock frequency of 20 MHz and supports supply voltages from 1.8V to 5.5V. The device features a write cycle time of 5ms, access time of 550 ns, and operates within a temperature range of -40°C to +85°C. It is housed in an 8-TSSOP surface-mount package.

Feature Summary

• Supports high-speed SPI communication up to 20 MHz
• Hardware write protection function
• Noise suppression function

Applications

• Data storage for embedded systems
• Configuration memory for microcontrollers
• Parameter storage in industrial control devices

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest documentation to confirm exact packaging or revision details. Ensure compatibility with 1.8V to 5.5V logic levels. Confirm RoHS3 compliance status if required for your assembly process. Cross-reference the 8-TSSOP footprint dimensions during PCB layout finalization.

Selection Notes

Select this component when SPI interface speed is prioritized over I2C compatibility. It is suitable for applications requiring hardware write protection and noise immunity. Verify that the system voltage falls within the 1.8V to 5.5V operating range. Consider the 8-TSSOP package constraints for board space limitations.

Part Context

This part belongs to the FT25C series of serial EEPROMs from Fremont Micro Devices. It offers higher speed performance compared to the I2C-based FT24C series. The device provides non-volatile data retention suitable for frequent read/write operations in consumer and industrial electronics.

Replacement Considerations

FT25C16A-ETR-T is listed as a parameter equivalent substitute.
