FT24C256A-USR-T

Overview

The FT24C256A-USR-T is a 256Kbit (32K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes 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 features a write cycle time of 5 ms. It is housed in an 8-SOP surface-mount package and supports an operating temperature range from -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 'USR' against official Fremont Micro Devices documentation to confirm the 8-SOP package variant. Ensure the component status is current, as availability may vary between distributors. Cross-reference the manufacturer part number with authorized channels to guarantee authenticity and compliance with RoHS standards before procurement.

Selection Notes

Select this component when a 256Kbit capacity is required with I²C connectivity. The 8-SOP package suits space-constrained surface-mount designs. Verify that the system voltage falls within the 1.8V to 5.5V range and that the I²C bus speed requirements do not exceed 1 MHz. Consider the -40°C to 85°C industrial temperature rating for environmental suitability.

Part Context

This part belongs to the FT24C256A series of serial EEPROMs from Fremont Micro Devices. The series offers various package options including TSSOP and SOP variants. The USR suffix specifically denotes the 8-SOP package type. These devices are designed for applications needing reliable, low-power non-volatile storage with simple serial interface protocols.

Replacement Considerations

FT24C256A-ETR-T: Same electrical specifications but in 8-TSSOP package. FT24C256A-USG-T: Same electrical specifications but in 8-SOIC package. Verify pinout compatibility and physical dimensions before substitution.
