FT24C256A-EDR-B

Overview

The FT24C256A-EDR-B 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. The device operates within a supply voltage range of 1.8V to 5.5V, offering an access time of 550 ns. It is housed in an 8-DIP package and supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Non-volatile memory storage retaining data without power
• I²C serial interface for simplified system integration
• Wide voltage operation supporting low-power applications

Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial sensors

Procurement Notes

Verify the specific suffix 'EDR-B' corresponds to the 8-DIP tube packaging when ordering. Confirm that the required I²C address matches your system design, as addresses may vary. Ensure the supply voltage range aligns with your target application's power rails before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring robust non-volatile storage in through-hole configurations. The 1 MHz I²C speed provides efficient data transfer rates compared to standard 400 kHz devices. Consider the 5 ms write cycle time when designing write-intensive operations to ensure adequate wait states are implemented.

Part Context

This part belongs to the FT24C256A series of serial EEPROMs from Fremont Micro Devices. It shares core electrical specifications with other variants like the USG-T and ETG-T but differs primarily in its physical package type. The EDR-B designation specifically identifies the through-hole DIP format suitable for prototyping or legacy board designs.

Replacement Considerations

• FT24C256A-USG-T
• FT24C256A-ETG-T
