FT24C128A-UDR-B

Overview

The FT24C128A-UDR-B is a 128Kbit (16K x 8) serial EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features a typical access time of 550 ns. The device operates within a supply voltage range of 1.8V to 5.5V and supports page write cycles. It is housed in an 8-DIP package and is rated for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Supports standard I²C serial communication protocol
• Non-volatile storage retains data without power
• Operates across wide voltage and temperature ranges

Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial instrumentation

Procurement Notes

Verify the specific suffix 'UDR-B' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the supplier provides original documentation from Fremont Micro Devices Ltd. Confirm that the component meets the required operating temperature range for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a 128Kbit capacity is required with I²C connectivity. Consider the 8-DIP package for through-hole mounting requirements. Evaluate the 1.8V to 5.5V operating range against system power rails. Verify that the 1 MHz bus speed meets the data throughput needs of the target application.

Part Context

This part belongs to the FT24C series of serial EEPROMs from Fremont Micro Devices Ltd. The series typically offers various capacities and packaging options, including surface-mount and through-hole configurations. The FT24C128A variant specifically denotes the 128Kbit density level within this product line.

Replacement Considerations

Cross-reference with other 128Kbit I²C EEPROMs from different manufacturers if availability is constrained. Ensure pin-to-pin compatibility and identical electrical specifications, particularly voltage range and interface timing, when substituting.
