FM25C020ULMT8

Memory IC Overview

The FM25C020ULMT8 is a 2-kbit serial electrically erasable programmable read-only memory (EEPROM) manufactured by Fairchild Semiconductor. It features an SPI 4-wire interface and operates within a supply voltage range of 2.7 V to 5.5 V. The device is organized as 256 x 8 bits and supports a maximum clock frequency of 1 MHz. It utilizes a TSSOP-8 surface-mount package and ensures data retention for up to 40 years. The component functions reliably across an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed synchronous serial communication via a standard four-wire SPI protocol.
• Provides hardware write protection capabilities through the dedicated WP pin.
• Ensures long-term non-volatile data storage with extended endurance cycles.

Memory IC Applications

• Industrial control systems requiring reliable parameter storage
• Consumer electronics needing configuration data retention
• Automotive modules demanding wide temperature operation

Memory IC Procurement Notes

Verify the specific suffix MT8 against official datasheets to confirm the exact tape-and-reel packaging quantity and lead time requirements. Confirm RoHS compliance status and end-of-life status directly with the manufacturer or authorized distributors, as availability may vary significantly across regions and supply channels.

Memory IC Selection Notes

Select this component when a compact 2-kbit non-volatile storage solution is required with SPI compatibility. Ensure the design accommodates the 2.7 V to 5.5 V supply range and the -40°C to +85°C industrial temperature environment. Verify that the TSSOP-8 footprint matches the PCB layout constraints and that the system logic levels are compatible with the specified voltage thresholds.

Memory IC Part Context

This EEPROM belongs to the FM25C series of serial memory devices designed for low-power applications. The series typically offers various capacities and interface options, including I2C and SPI variants. The FM25C020ULMT8 specifically addresses the need for small, robust data storage in space-constrained electronic designs where moderate speed and industrial reliability are prioritized over high-density capacity.

Memory IC Replacement Considerations

Check for direct cross-reference part numbers such as NM25C020LEM8 or other FM25C020 variants with different suffixes. Verify pinout compatibility and electrical specifications before substitution. Ensure any replacement maintains the same SPI interface protocol and voltage operating ranges to guarantee functional equivalence in the existing circuit design.
