FT24C08A-ETR-T

Overview

The FT24C08A-ETR-T is an 8-Kbit (1K x 8) serial EEPROM from Fremont Micro Devices Ltd, utilizing a standard two-wire I2C interface. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 1 MHz at 5V or 400 kHz at lower voltages. The device features a 16-byte page write mode with a self-timed write cycle of 5ms maximum. It includes hardware write protection and is available in compact surface-mount packages such as TSOT-23-5 and DFN variants, designed for industrial temperature ranges.

Feature Summary

• Supports standard two-wire bi-directional serial communication compatible with I2C bus modes
• Features hardware write protect pin for data security
• Includes Schmitt trigger inputs for noise filtering
• Offers high reliability with significant endurance cycles

Applications

• Consumer electronics requiring non-volatile data storage
• Industrial control systems needing parameter retention
• Smart cards and identification devices
• Portable battery-powered equipment

Procurement Notes

Verify the specific package suffix (e.g., ETR vs UPR/UNR) against the manufacturer's current datasheet to ensure physical compatibility. Confirm that the operating voltage requirements align with the target system's power rails, particularly noting the frequency limitations at lower voltages. Ensure the design accounts for the required pull-up resistors on the serial interface lines.

Selection Notes

Select this component when a small footprint is required alongside low-power operation. The 1.8V minimum voltage makes it suitable for modern low-voltage logic families. Consider the 16-byte page write capability for efficient data handling. Verify that the specific package variant meets the PCB layout constraints and thermal requirements of the application environment.
