FT24C32A-USG-T

Overview

The FT24C32A-USG-T is a 32-Kbit serial I²C bus EEPROM manufactured by Fremont Micro Devices Ltd. Organized as 4K x 8 bits, this non-volatile memory device supports standard (100 kHz), fast (400 kHz), and fast mode plus (1 MHz) communication protocols. It operates within a supply voltage range of 1.8V to 5.5V and features an access time of 550 ns. The component is housed in an 8-SOP surface-mount package and is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports high-speed I²C communication with Fast Mode Plus compatibility
• Provides hardware write protection capabilities via dedicated control pin
• Ensures data retention through robust non-volatile storage architecture

Applications

• Industrial control systems requiring reliable parameter storage
• Consumer electronics utilizing low-voltage logic interfaces
• Automotive modules needing extended temperature range operation

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure the supplier provides traceability documentation for RoHS compliance. Cross-reference the manufacturer's active status to guarantee long-term availability for production runs.

Selection Notes

Select this component when a small footprint is required alongside high-speed data transfer needs. It is suitable for designs operating between 1.8V and 5.5V where I²C bus compatibility is mandatory. Consider its industrial temperature rating for environments exceeding standard commercial limits.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs from Fremont Micro Devices. These devices are engineered to replace legacy parallel EEPROMs by reducing pin counts while maintaining data integrity. The series offers various densities optimized for embedded memory applications.

Replacement Considerations

Check pinout compatibility with existing PCB layouts before substitution. Verify that the replacement device supports the same I²C clock frequencies and voltage levels required by the host controller.
