FT24C256A-UTR-T

Overview

The FT24C256A-UTR-T is a serial EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It provides a storage capacity of 256 Kbit, organized as 32K x 8 bits. The device utilizes an I²C interface with a maximum clock frequency of 1 MHz and features an access time of 550 ns. It operates within a supply voltage range of 1.8V to 5.5V and supports page write cycles of 5 ms. The component is housed in an 8-TSSOP package (0.173"/4.40mm width) and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Serial electrical erasable and programmable read-only memory architecture
• I²C bus compatible interface supporting standard and high-speed modes
• Wide operating voltage range enabling compatibility with various logic levels
• Non-volatile data retention without requiring power for storage

Applications

• Data logging systems requiring persistent parameter storage
• Consumer electronics configuration memory
• Industrial control system calibration data retention
• Embedded devices needing small-scale non-volatile storage

Procurement Notes

Verify the specific suffix 'UTR-T' corresponds to the 8-TSSOP package and tape-and-reel packaging format. Confirm that the manufacturer Fremont Micro Devices Ltd is the authorized source for this part number. Ensure the ordering information matches the required voltage and temperature specifications before procurement.

Selection Notes

Select this component when a low-pin-count serial memory solution is required for space-constrained designs. The I²C interface minimizes board routing complexity compared to parallel memories. Consider the 1.8V to 5.5V operating range for flexibility in mixed-voltage systems. Verify that the 550 ns access time meets the system's timing requirements.

Part Context

This part belongs to the FT24C256A series of serial EEPROMs from Fremont Micro Devices. The series offers varying package options including TSSOP and SOP formats. These components are designed for general-purpose non-volatile storage applications where moderate speed and low power consumption are prioritized over high-density bulk storage.

Replacement Considerations

Compatible substitutes include other 256K-bit I²C EEPROMs from manufacturers such as Microchip or STMicroelectronics. Ensure pinout compatibility and voltage level matching when replacing. Verify that the substitute device supports the same I²C addressing scheme and page write sizes.
