FT24C32A-UTR-T

Overview

The FT24C32A-UTR-T is a 32-kilobit (4K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features a write cycle time of 5 ms. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an industrial temperature range from -40°C to +85°C. It is housed in an 8-SOP package.

Feature Summary

• Supports high-speed I²C communication up to 1 MHz
• Provides non-volatile data retention across wide voltage ranges
• Includes hardware write protection capabilities

Applications

• Data logging systems requiring persistent storage
• Configuration memory for embedded controllers
• Parameter storage in consumer electronics

Procurement Notes

Verify the specific suffix 'UTR' against official Fremont Micro Devices documentation to confirm tape-and-reel packaging and pin configuration. Ensure the selected variant matches the required operating voltage and temperature specifications for your target application environment before finalizing procurement.

Selection Notes

Select this component when a 32-kilobit capacity is required alongside fast 1 MHz I²C performance. It is suitable for designs needing operation down to 1.8 V. Compare against standard 400 kHz variants if higher speed is critical, or lower density parts if cost reduction is the primary driver.

Part Context

This part belongs to the FT24C32A series of serial EEPROMs. It shares architectural similarities with other industry-standard 2-wire bus devices but offers specific electrical characteristics defined by Fremont Micro Devices. The 8-SOP package allows for compact surface-mount integration.

Replacement Considerations

Direct substitutes include the FT24C32A-ESG-T and FT24C32A-ENR-T from the same manufacturer family. Cross-brand replacements such as the AT24C32 or M24C32 may be compatible but require verification of voltage levels and timing parameters.
