FT24C04A-KDR-B

Overview

The FT24C04A-KDR-B is a non-volatile EEPROM memory integrated circuit manufactured by Fremont Micro Devices Ltd. It offers a storage capacity of 4Kb, organized as 512 words by 8 bits. The device utilizes an I2C serial interface with a maximum clock frequency of 1 MHz and features a fast access time of 550 ns. It operates within a supply voltage range of 1.8V to 5.5V and supports a write cycle time of 5ms. The component is housed in an 8-DIP package with a pin spacing of 7.62mm (0.300 inches) and is rated for operation between -40°C and 85°C.

Feature Summary

• Non-volatile data retention capability preserving stored information without power
• I2C serial communication interface supporting standard and high-speed modes
• Wide operating voltage range compatible with various logic levels
• Robust industrial temperature rating for diverse environmental conditions

Applications

• Data logging systems requiring persistent storage of sensor readings
• Configuration parameter storage in embedded control units
• Calibration data retention for precision measurement instruments
• Device identification and serial number storage in manufacturing lines

Procurement Notes

Verify the specific package variant, as the KDR suffix denotes an 8-DIP tube package. Confirm RoHS3 compliance status for regulatory requirements. Ensure the ordering code matches the exact speed grade and voltage specifications required by the design. Cross-reference the manufacturer part number with distributor listings to confirm current availability and authenticity before finalizing procurement.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or legacy board designs. The 4Kb capacity suits applications needing moderate data persistence. The wide voltage range allows flexibility in power supply design. Consider the 1 MHz I2C speed limit for system timing constraints. Verify that the physical dimensions of the 8-DIP package fit the available PCB real estate and mounting requirements.

Part Context

This part belongs to the FT24C04A family of serial EEPROMs from Fremont Micro Devices Ltd. The family includes variants with different packaging options such as DFN, TSSOP, SOP, and DIP. The core electrical characteristics remain consistent across the family, differing primarily in physical form factor and pin configuration. This specific model provides a traditional dual-in-line package option for easier handling during assembly.

Replacement Considerations

Direct substitutes include other 4Kb I2C EEPROMs in 8-DIP packages from manufacturers like STMicroelectronics or Microchip. Ensure compatibility regarding I2C address bits and command sets. Verify that the replacement part meets the same voltage and temperature specifications. Check if the substitute requires any level shifting or pull-up resistor adjustments.
