FT24C128A-UTG-T

Overview

The FT24C128A-UTG-T is a 128Kb (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. The device operates within a supply voltage range of 1.8V to 5.5V and offers an access time of 550 ns. It is housed in an 8-TSSOP package and supports operation across a temperature range of -40°C to 85°C.

Feature Summary

• Non-volatile memory storage utilizing EEPROM technology for data retention without power.
• Serial communication via I²C bus interface supporting standard and high-speed modes.
• Wide operating voltage compatibility ranging from 1.8V to 5.5V for diverse system integration.

Applications

• Data logging systems requiring non-volatile parameter storage
• Consumer electronics configuration memory
• Industrial control system calibration data retention

Procurement Notes

Verify the specific suffix UTG against official Fremont Micro Devices documentation to confirm the 8-TSSOP package variant. Ensure the component meets RoHS3 compliance requirements if mandated by your assembly standards. Cross-reference the manufacturer part number with authorized distributor databases to confirm current availability status, as supply conditions may vary.

Selection Notes

Select this component when a 128Kb capacity is required alongside I²C connectivity. The 1.8V to 5.5V operating range allows flexibility in low-power and standard voltage designs. Consider the 8-TSSOP package dimensions for PCB layout constraints and verify that the 1 MHz clock speed aligns with the system's bus timing requirements.
