FT24C32A-ESG-T

Overview

The FT24C32A-ESG-T is a 32-kbit (4K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features a write cycle time of 5 ms for both word and page operations. The component offers an access time of 500 ns and operates within a supply voltage range of 1.8V to 5.5V. Designed for surface mount applications, it is housed in an 8-SOIC package measuring 3.90 mm in width. The device supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed I²C communication with a maximum clock frequency of 1 MHz
• Provides non-volatile data storage with fast 5 ms write cycle times
• Operates across a wide supply voltage range from 1.8V to 5.5V
• Includes hardware write protection capabilities for memory security

Applications

• Data logging systems requiring persistent storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial sensors
• Device identification and serialization in manufacturing

Procurement Notes

Verify the specific suffix ESG-T corresponds to the 8-SOIC package and cut tape packaging format when sourcing. Confirm that the 1 MHz clock speed requirement aligns with the system bus specifications. Ensure the 1.8V minimum operating voltage is compatible with the target logic levels. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a compact 8-pin SOIC footprint is required for 32-kbit storage. Consider the 1 MHz I²C speed for applications needing faster data throughput than standard 400 kHz devices. Evaluate the 1.8V lower voltage limit against system power rails. Compare the 500 ns access time against system timing constraints to ensure adequate performance margins.

Part Context

This part belongs to the FT24C32 series of serial EEPROMs from Fremont Micro Devices Ltd. It shares core electrical characteristics with other variants in the family, differing primarily in package type and shipping configuration. The series provides a cost-effective solution for low-density non-volatile memory needs in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other FT24C32A variants with different packages such as FT24C32A-UTG-T (TSSOP). Cross-brand replacements must match the 32-kbit capacity, I²C interface, and 1.8V-5.5V voltage range. Verify pin compatibility and software register alignment before integrating alternative components.
