FT24C32A-UTR-B

Overview

The FT24C32A-UTR-B is a 32Kbit (4k x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 800 kHz and features a write cycle time of 5 ms. The device operates within a supply voltage range of 1.8V to 5.5V and has an access time of 700 ns. It is housed in an 8-TSSOP surface-mount package and supports operation across a temperature range of -40°C to 85°C.

Feature Summary

• Supports two-wire serial communication via the I²C bus protocol for efficient data transfer.
• Enables page write operations with a capacity of 32 bytes per page to optimize write performance.
• Operates on low voltage power supplies ranging from 1.8V to 5.5V for versatile integration.

Applications

• Data storage in consumer electronics requiring non-volatile memory retention
• Configuration parameter storage in industrial control systems
• Calibration data preservation in embedded sensor modules

Procurement Notes

Verify the specific suffix 'B' against official Fremont documentation to confirm pinout and electrical characteristics, as suffixes often denote package variations or tape-and-reel specifications. Ensure compatibility with your system's I²C voltage levels and check for obsolescence status before finalizing procurement plans.

Selection Notes

Select this component when a compact 32Kbit EEPROM solution is required for I²C-based designs. The 8-TSSOP package suits space-constrained applications. Consider the 800 kHz speed limit and 5 ms write time when designing for high-throughput data logging scenarios.

Part Context

This part belongs to the FT24C32A series of serial EEPROMs from Fremont Micro Devices. The series offers various package options including SOP and DIP variants. The UTG and ESG suffixes indicate different physical packages such as TSSOP and SOIC, while the R typically denotes reel packaging configuration.

Replacement Considerations

Direct substitutes include other 32Kbit I²C EEPROMs from Fremont such as the FT24C32A-ESR-B or FT24C32A-UDR-B, provided the package type matches the PCB footprint requirements. Verify pin compatibility before substitution.
