FT24C128A-USG-T

Overview

The FT24C128A-USG-T is a 128Kbit (16K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features a write cycle time of 5 ms per word or page. The device offers an access time of 550 ns and operates within a supply voltage range of 1.8V to 5.5V. It is housed in an 8-SOP package, specifically an 8-SOIC with a width of 0.154 inches (3.90 mm). The component supports surface mount installation and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Supports standard two-wire bidirectional serial communication via the I²C interface.
• Includes hardware data protection mechanisms to prevent accidental writes.
• Features self-timed write cycles for efficient operation without external timing control.

Applications

• Low voltage and low power electronic systems
• Data storage requiring non-volatile memory retention
• Industrial applications operating within extended temperature ranges

Procurement Notes

Verify the specific suffix 'USG' against official Fremont Micro Devices documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with system voltage levels between 1.8V and 5.5V. Confirm that the I²C address configuration meets design requirements. Check for RoHS compliance status if required by regulatory standards. Validate lead times as availability may vary.

Selection Notes

Select this component when a 128Kbit capacity is required with I²C connectivity. Consider the 8-SOP package for PCB layout constraints. Evaluate the 1 MHz clock speed against system bus requirements. Ensure the operating temperature range aligns with the application environment. Compare power consumption metrics if battery life is critical.
