FT24C32A-UNR-T

Overview

The FT24C32A-UNR-T is a 32Kbit (4K x 8) CMOS Serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 800 kHz and an access time of 700 ns. The device operates within a supply voltage range of 1.8V to 5.5V and supports page writes with a write cycle time of 5 ms. It is housed in an 8-DFN surface-mount package and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Non-volatile data retention capability for persistent storage
• I²C serial interface compatibility for system integration
• Wide operating voltage range supporting low-power applications

Applications

• Data logging systems requiring non-volatile memory
• Consumer electronics configuration storage
• Industrial control parameter retention

Procurement Notes

Verify the specific suffix UNR-T corresponds to the 8-DFN package and 800kHz speed grade. Confirm that the ordering information matches the required tape-and-reel packaging format. Ensure the component meets the specified electrical characteristics for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a compact 32Kbit EEPROM with I²C connectivity is required. The 8-DFN package suits space-constrained designs. Verify that the 800kHz clock speed and 1.8V-5.5V voltage range align with the system bus and power supply specifications.

Part Context

This part belongs to the FT24CxxA series of CMOS Serial EEPROMs from Fremont Micro Devices. These devices are designed for high-density, low-voltage applications. The series typically includes variants with different capacities and package options, all sharing similar I²C interface protocols and operational characteristics.

Replacement Considerations

Compatible substitutes include other 32Kbit I²C EEPROMs from manufacturers such as Microchip or STMicroelectronics, provided they match the 8-DFN package and electrical specifications.
