FT24C64A-ETR-T

Overview

The FT24C64A-ETR-T is a 64Kbit (8K x 8) serial I²C EEPROM manufactured by Fremont Micro Devices Ltd. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 1MHz. The device features a maximum access time of 500ns and a write cycle time of 5ms for both word and page operations. It is housed in an 8-TSSOP package with dimensions of 0.173 inches (4.40mm) width. The component is rated for an operating temperature range of -40°C to +85°C and utilizes surface mount installation.

Feature Summary

• Supports standard I²C bus communication protocols including 100 kHz, 400 kHz, and high-speed 1 MHz modes.
• Provides non-volatile data storage with electrically erasable programmable memory architecture.
• Includes enhanced electrostatic discharge and latch-up protection mechanisms.

Applications

• Data logging systems requiring persistent storage of sensor readings or operational parameters.
• Configuration storage for embedded controllers and microcontroller-based devices.
• Calibration data retention in industrial instrumentation and metering equipment.

Procurement Notes

Verify the specific suffix 'ETR' corresponds to the 8-TSSOP package variant when sourcing, as other suffixes may indicate different packaging such as DFN or TDFN. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the ordering quantity aligns with the manufacturer's standard reel size to avoid partial reel handling issues during assembly.

Selection Notes

Select this component when a balance between moderate storage density and low pin count is required for space-constrained designs. The wide supply voltage range allows compatibility with both 1.8V and 5V logic systems without level shifting. Consider the 5ms write cycle time when designing software routines to ensure adequate delays are implemented between consecutive write operations to prevent data corruption.

Part Context

This part belongs to the FT24CxA series of serial EEPROMs from Fremont Micro Devices Ltd, which offers various capacities ranging from 2Kbit to 256Kbit. The series shares common interface characteristics but differs in memory organization and physical packaging options. The ETR suffix specifically denotes the TSSOP package configuration within this product line.

Replacement Considerations

Direct substitutes include the FT24C64A-ENR-T, which offers identical electrical specifications but utilizes an 8-DFN package. Designers must verify footprint compatibility if replacing on existing PCBs. Other capacity variants within the same family require code adjustments due to differing address structures.
