FT24C32A-USR-T

Overview

The FT24C32A-USR-T is a 32Kbit (4K x 8) serial EEPROM memory device manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features an access time of 500 ns. The device operates within a supply voltage range of 1.8V to 5.5V and supports page write cycles of 5 ms. It is housed in an 8-SOP package with a width of 0.154 inches (3.90 mm). The component is designed for industrial applications, functioning reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides non-volatile data storage using EEPROM technology
• Supports standard I²C serial communication protocol
• Operates with wide supply voltage compatibility from 1.8V to 5.5V

Applications

• Data logging systems requiring persistent storage
• Configuration parameter retention in embedded controllers
• Calibration data storage in sensor modules

Procurement Notes

Verify the specific suffix 'USR-T' against official Fremont Micro Devices documentation to confirm the exact package type and tape/reel specifications. Ensure the selected variant matches the required operating temperature range and voltage levels for the target application environment before finalizing procurement.

Selection Notes

Select this component when a 32Kbit capacity is required with I²C connectivity. Consider the 8-SOP package dimensions for PCB layout constraints. Verify that the 1 MHz clock speed meets system timing requirements and that the 1.8V to 5.5V supply range aligns with the host controller's power rails.

Part Context

This part belongs to the FT24C32A series of serial EEPROMs from Fremont Micro Devices. The series offers various package options including SOP, TSSOP, and DFN variants. These devices are designed for general-purpose non-volatile memory applications where moderate density and reliable data retention are necessary.

Replacement Considerations

Cross-reference with other FT24C32A variants such as FT24C32A-ESG-T or FT24C32A-UTG-T if package differences are acceptable. Verify pinout compatibility and electrical specifications before substituting.
