FT24C32A-UDR-B

Overview

The FT24C32A-UDR-B is a 32Kbit (4k x 8) EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It features an I²C interface with a maximum clock frequency of 800 kHz and a typical access time of 700 ns. The device operates within a supply voltage range of 1.8V to 5.5V and supports a write cycle time of 5 ms. It is housed in an 8-DIP package, suitable for through-hole mounting, and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Non-volatile storage capability preserving data without power
• I²C serial interface compatibility for simplified system integration
• Wide operating voltage range supporting diverse logic levels

Applications

• Data logging systems requiring non-volatile parameter storage
• Embedded controllers needing configuration retention
• Industrial equipment memory modules

Procurement Notes

Verify the specific suffix 'UDR-B' corresponds to the 8-DIP package and 800 kHz speed variant. Confirm that the manufacturer Fremont Micro Devices Ltd is the authorized source for this part number. Ensure the ordering documentation explicitly lists the 32Kbit capacity and I²C protocol support to avoid substitution errors with higher-speed or different package variants.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or legacy board designs. The 800 kHz speed is sufficient for most standard I²C bus applications. Consider the 1.8V minimum voltage for low-power operation. Verify that the 5 ms write cycle time aligns with the application's timing constraints for data persistence.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs from Fremont Micro Devices Ltd. These devices are designed as drop-in replacements for industry-standard I²C EEPROMs. The series offers various capacities and package options, with the UDR-B specifically denoting the 32Kbit density in an 8-pin dual in-line package.

Replacement Considerations

Compatible substitutes include other 32Kbit I²C EEPROMs in 8-DIP packages, such as the AT24C32N or 24LC32B, provided the pinout and electrical characteristics match. Verify that alternative parts support the same 1.8V to 5.5V voltage range and 800 kHz clock speed.
