FT24C256A-UTG-T

Overview

The FT24C256A-UTG-T is a 256Kb (32K 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 for both word and page operations. The device offers an access time of 550 ns and operates within a supply voltage range of 1.8V to 5.5V. It is housed in an 8-TSSOP package and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Non-volatile memory storage capability preserving data without power
• Serial I²C communication interface supporting standard and high-speed modes
• Wide operating voltage range compatible with various logic levels
• Surface-mount packaging suitable for automated assembly processes

Applications

• Data logging systems requiring non-volatile parameter storage
• Consumer electronics configuration memory
• Industrial control system calibration data retention
• Embedded devices storing firmware version or identification codes

Procurement Notes

Verify the specific suffix 'UTG-T' against official Fremont Micro Devices documentation, as local sources primarily list 'UTG-B'. Confirm package dimensions and pinout compatibility with existing PCB footprints. Ensure the supplier provides valid RoHS compliance certificates and traceability records for quality assurance purposes before finalizing procurement orders.

Selection Notes

Select this component when a 256Kb capacity is required with I²C connectivity. The 1.8V to 5.5V voltage range allows flexibility in low-power and standard logic designs. Consider the 8-TSSOP package constraints for board space. Compare access times and write cycle durations against application timing requirements to ensure adequate performance margins for frequent update scenarios.

Part Context

This part belongs to the FT24C256A series of serial EEPROMs from Fremont Micro Devices. The series typically includes variants with different packages such as SOIC and TSSOP, and suffixes indicating tape-and-reel or tube packaging. These devices are designed for general-purpose non-volatile memory applications where moderate density and reliable data retention are essential.

Replacement Considerations

Publicly confirmed substitute part numbers for FT24C256A-UTG-T were not found in the provided source material. Verify compatibility with other 256Kb I²C EEPROMs from different manufacturers only if pinouts and electrical characteristics match exactly.
