Product details

FRAM with SPI — what it replaces on the BOM

The Cypress FM25L16B-DGTR is a 16Kbit non-volatile memory using ferroelectric RAM (FRAM) technology, organised as 2K x 8 bits and accessed through an SPI bus at up to 20 MHz.

Package and thermal — 8-DFN with exposed pad

The FM25L16B-DGTR comes in an 8-WDFN package with an exposed thermal pad (supplier device package 8-DFN 4x4.5 mm).

For new designs this means no forced requalification horizon; for production lines it removes the single-source lifecycle risk that often drives emergency broker buys.

Sourcing — qualified and quoted to order

The active lifecycle means it remains a standard catalog item, not a shortage-era allocation play. For BOM planning, the FM25L16B-DGTR can be dual-sourced within the same family footprint if a second FRAM vendor is needed, though no pin-compatible second source is recorded in this ledger.

Frequently asked questions

What is the write endurance of FM25L16B-DGTR?

FRAM technology provides essentially unlimited write endurance — the datasheet specifies 10^14 read/write cycles, compared to 1 million cycles typical for EEPROM. No wear-leveling is needed.

Is FM25L16B-DGTR compatible with 3.3V logic?

Yes, the supply range is 2.7V to 3.6V, which covers 3.3V logic levels directly. The SPI inputs are 3.3V-tolerant within that supply window.

Does FM25L16B-DGTR have ECC or error correction?

The evidence does not list ECC support. FRAM cells are inherently more radiation-tolerant than Flash, but no on-chip error correction is claimed in the available specifications.
