FT24C256A-ESG-T

Overview

The FT24C256A-ESG-T is a 256Kbit serial EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It features an I²C interface with a maximum clock frequency of 1 MHz and an access time of 550 ns. The device operates within a supply voltage range of 1.8V to 5.5V and supports page write cycles of 5 ms. It is housed in an 8-SOP package with a width of 3.90 mm and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Non-volatile data storage capability retaining information without power
• Serial I²C bus interface for efficient communication
• Wide operating voltage range supporting low-power applications

Applications

• Embedded systems requiring persistent data retention
• Consumer electronics storing configuration parameters
• Industrial control devices needing reliable memory

Procurement Notes

Verify the specific suffix ESG-T confirms the 8-SOP package variant during sourcing. Confirm RoHS compliance status if required for your assembly process. Ensure the supplier provides official datasheets matching the Fremont Micro Devices Ltd part number to avoid counterfeit components. Check lead times as availability may vary by region.

Selection Notes

Select this component when a 256Kbit capacity is required with I²C connectivity. The 8-SOP package suits surface-mount designs with moderate pin count needs. Consider the 1.8V to 5.5V operating range for compatibility with various logic levels. Verify thermal requirements against the -40°C to 85°C industrial grade specification.

Part Context

This part belongs to the FT24C256A series of serial EEPROMs from Fremont Micro Devices. The series offers non-volatile memory solutions using standard I²C protocols. Other variants in the family differ primarily in packaging options such as TSSOP or DFN, while maintaining identical electrical characteristics and memory architecture.

Replacement Considerations

FT24C256A-USG-T: Identical electrical specifications but packaged in 8-SOIC instead of 8-SOP. Pinout compatibility should be verified before substitution due to potential footprint differences.
