FT24C64A-ESG-B

Overview

The FT24C64A-ESG-B is a 64-Kbit serial electrically erasable programmable read-only memory (EEPROM) manufactured by Fremont Micro Devices Ltd. It features an I²C compatible interface with a maximum clock frequency of 1 MHz and operates within a supply voltage range of 1.8 V to 5.5 V. The device is organized as 8 K × 8 bits and utilizes an 8-SOP package with a width of 3.90 mm. It supports byte and page write operations, with a typical write cycle time of 5 ms per word or page. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports standard I²C bus protocol for serial data communication
• Provides non-volatile storage capability for persistent data retention
• Enables software-configurable device addressing via hardware pins
• Offers internal write protection mechanisms to prevent accidental data modification

Applications

• Consumer electronics requiring small data storage
• Industrial control systems needing parameter logging
• Automotive modules for configuration data storage
• Smart metering devices for usage record keeping

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the ordering code matches the exact voltage and temperature grade required for your design. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and avoid counterfeit components. Check for any recent revisions that might affect electrical characteristics or mechanical tolerances before finalizing procurement.

Selection Notes

Select this component when a compact 64-Kbit EEPROM with I²C interface is required. It is suitable for applications needing low power consumption and high reliability in harsh environments. Consider the 8-SOP package size for PCB layout constraints. Verify that the system voltage falls within the 1.8 V to 5.5 V operating range. Ensure the I²C bus speed requirements do not exceed the device's maximum clock frequency specifications.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs from Fremont Micro Devices. These devices are designed for general-purpose non-volatile memory applications. They share common interface protocols and organizational structures within the family. The ESG-B suffix indicates specific packaging and tape-and-reel options. This series competes with similar I²C EEPROMs from other manufacturers offering comparable capacities and performance levels.

Replacement Considerations

Direct replacements may include FT24C64A-ESG-T if tape-and-reel packaging is preferred over bulk. Verify pin-to-pin compatibility with other 64-Kbit I²C EEPROMs from different vendors only after confirming identical electrical parameters and package dimensions. Ensure substitute parts meet the same temperature and voltage specifications.
