FT24C256A-ETG-T

Overview

The FT24C256A-ETG-T is a 256Kb (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 with a width of 4.40 mm and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Non-volatile memory storage utilizing EEPROM technology
• Serial communication via I²C bus interface
• Surface mount construction in compact TSSOP packaging

Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter retention in embedded devices
• Calibration data storage for sensor modules

Procurement Notes

Verify the specific suffix ETG-T against official Fremont Micro Devices documentation to confirm the 8-TSSOP package variant. Ensure compatibility with system voltage levels between 1.8V and 5.5V. Confirm that the I²C address configuration meets design requirements before procurement.

Selection Notes

Select this component when a 256Kb capacity is required with I²C connectivity. The 1.8V to 5.5V operating range allows flexibility in low-power and standard logic designs. The 8-TSSOP package is suitable for space-constrained surface-mount applications requiring robust thermal performance up to 85°C.

Part Context

This part belongs to the FT24C256A series of serial EEPROMs from Fremont Micro Devices. The series provides various package options including TSSOP and SOIC variants. The FT24C256A-ETG-T specifically denotes the tape-and-reel version in the 8-TSSOP form factor, designed for automated assembly processes.

Replacement Considerations

Cross-reference with other FT24C256A variants such as FT24C256A-ETR-T or FT24C256A-USG-T if package differences are acceptable. Verify pinout compatibility and electrical specifications match before substituting.
