FT24C08A-ETG-T

Overview

The FT24C08A-ETG-T is an 8-Kbit (1024 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I²C bi-directional serial interface for data transfer. The device operates within a supply voltage range of 1.8V to 5.5V, supporting clock frequencies up to 1 MHz at 5V and 400 kHz at lower voltages. It features hardware write protection, self-timed write cycles with a maximum duration of 5ms, and high endurance of typically one million write/erase cycles. The component is housed in an 8-pin TSSOP package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports standard two-wire bi-directional serial interface compatible with I²C protocols
• Features hardware write protect pin for secure data storage management
• Includes internally organized page write mode allowing partial page operations
• Provides high reliability with long data retention and high cycle endurance

Applications

• Consumer electronics requiring non-volatile parameter storage
• Industrial control systems needing reliable data logging
• Smart cards and security tokens utilizing hardware write protection
• Portable devices operating on low voltage power supplies

Procurement Notes

Verify the specific suffix ETG-T corresponds to the 8-pin TSSOP package configuration as documented in official Fremont Micro Devices datasheets. Confirm that the ordering part number matches the required voltage and speed grades. Ensure compliance with RoHS directives if environmental standards are mandatory for the target assembly process.

Selection Notes

Select this component when a compact surface-mount solution is required for small capacity non-volatile memory applications. The wide supply voltage range allows compatibility with both 1.8V and 5V logic systems. Consider the 8-pin TSSOP footprint for PCB layout constraints where space is limited but through-hole packages are unsuitable.

Part Context

This part belongs to the FT24C08A series of serial EEPROMs from Fremont Micro Devices. The series includes variants with different package options such as DIP, SOP, and SOT-23. The FT24C08A-ETG-T specifically denotes the TSSOP package variant within this family, sharing core electrical characteristics with other members like the FT24C08A-USG-T.

Replacement Considerations

Compatible substitutes include the AT24C08C and CAT24C08 series from other manufacturers. Verify pinout compatibility and voltage specifications before substitution. Ensure the replacement part supports the same I²C addressing scheme and write cycle timing requirements.
