FT24C128A-UTR-B

Overview

The FT24C128A-UTR-B is a 128Kbit (16K x 8) Two-Wire Serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features a fast 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-TSSOP surface-mount package and is rated for operation across an extended temperature range of -40°C to +85°C.

Feature Summary

• Supports standard I²C two-wire serial communication protocol
• Provides non-volatile data retention without power
• Operates across a wide supply voltage range from 1.8V to 5.5V
• Available in compact 8-TSSOP surface-mount packaging

Applications

• Data storage in embedded systems requiring non-volatile memory
• Configuration parameter storage in industrial control devices
• Calibration data retention in sensor modules
• Device identification and serial number storage in consumer electronics

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications, as suffixes may indicate variations in tape-and-reel quantity or RoHS status. Ensure the I²C address configuration matches your system design requirements before integration.

Selection Notes

Select this component when a 128Kbit capacity is required with I²C interface compatibility. Consider the 1.8V minimum operating voltage for low-power applications. The 8-TSSOP package is suitable for space-constrained PCB layouts. Verify that the 1 MHz clock speed meets the system's data throughput needs.

Part Context

This part belongs to the FT24C128A series of Two-Wire Serial EEPROMs from Fremont Micro Devices. The series offers various package options including TSSOP and DIP variants. The 'UTR' designation typically indicates the TSSOP package type with specific reel packaging, while 'B' may denote a specific revision or environmental compliance status.

Replacement Considerations

Cross-reference with other 128Kbit I²C EEPROMs such as the AT24C128 or M24C128 for pin-compatible alternatives. Ensure voltage levels and I²C timing parameters match the original design constraints before substituting.
