FT24C256A-ETR-T

Overview

The FT24C256A-ETR-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 features a write cycle time of 5 ms for both word and page operations. The device offers an access time of 550 ns and operates within a supply voltage range of 1.8V to 5.5V. It is housed in an 8-TSSOP package (4.40mm width) designed for surface mount installation. The component supports non-volatile data storage across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed I²C communication with a maximum clock frequency of 1 MHz
• Provides reliable non-volatile data retention using EEPROM technology
• Operates effectively across a wide supply voltage range from 1.8V to 5.5V

Applications

• Data logging systems requiring persistent storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation

Procurement Notes

Verify the specific suffix ETR-T corresponds to the 8-TSSOP package and tape-and-reel packaging configuration. Confirm that the manufacturer status remains active, as availability may vary. Ensure compatibility with the target system's I²C bus voltage levels and physical footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 256Kbit capacity is required alongside standard I²C connectivity. The 1.8V to 5.5V operating range allows flexibility in low-power or mixed-voltage designs. The 8-TSSOP package is suitable for space-constrained surface-mount applications. Consider the 5ms write cycle time when designing write-intensive workflows.

Part Context
