FT24C32A-ETR-T

Overview

The FT24C32A-ETR-T is a serial EEPROM manufactured by Fremont Micro Devices Ltd, organized as 4K x 8 bits with a total storage capacity of 32 kilobits. It utilizes an I²C interface supporting a maximum clock frequency of 1 MHz and features a write cycle time of 5 ms for both word and page operations. The device offers an access time of 700 ns and operates within a supply voltage range of 1.8V to 5.5V. Packaged in an 8-TSSOP surface-mount format, it supports an industrial 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 retention using EEPROM technology
• Features hardware write protection capabilities for the memory array

Applications

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

Procurement Notes

Verify the specific suffix ETR-T confirms the tape-and-reel packaging configuration required for automated assembly processes. Ensure the component meets RoHS3 compliance standards if mandated by your manufacturing regulations. Cross-reference the manufacturer part number against official distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a 32-kilobit EEPROM is required with I²C connectivity and operation down to 1.8 volts. The 8-TSSOP package is suitable for space-constrained designs needing surface-mount integration. Consider the 700 ns access time and 5 ms write cycle duration against system timing requirements to ensure compatibility with the host controller's bus speed.

Part Context

This part belongs to the FT24C32A series of serial EEPROMs from Fremont Micro Devices Ltd. It shares architectural similarities with other members like the FT24C256A and FT24C16A, differing primarily in storage density and package options. The series is designed for general-purpose non-volatile memory applications in consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully when considering cross-brand alternatives such as the M24C32 or FM24C32, as voltage ranges and interface speeds may differ.
