|---|---|---|---|---|
| FFF Compatibility | The pinout is identical to the target part, with standard SPI pins on pins 1 to 8 in an 8-SOIC/SOP package format.The 8-pin SOP/SOIC package footprint is identical (3.90 mm body width, 1.27 mm pin pitch).Meets or exceeds all performance, timing, and electrical characteristics, including operating voltage support down to 2.7V. | The pinout is completely identical to the target part's standard SPI interface layout.Housed in the identical 8-SOIC narrow package (3.90 mm width, 1.27 mm pitch).The supply voltage is limited to 3.0V ~ 3.6V (original supports 2.7V ~ 3.65V) and the maximum frequency is 16 MHz (original is 20 MHz). | ||
 AI Summary | FM25CL64B-G by Infineon Technologies: FRAM (Ferroelectric RAM) Memory IC 64Kbit SPI 20 MHz 8-SOIC. | This RAMXEED (formerly Fujitsu) part is an exceptional F-RAM alternative that matches the ferroelectric RAM technology, offering infinite read/write cycles and instant writes. It completely covers the original 2.7V to 3.65V supply range and even supports faster clock frequencies. It serves as a direct drop-in physical and electrical replacement.
| This automotive-grade F-RAM from the same manufacturer serves as a high-reliability sibling option. While it is pin-compatible and uses the same non-volatile F-RAM technology, the supply voltage is narrower (3.0V minimum compared to 2.7V) and the clock frequency is slightly lower at 16 MHz, making it a partial functional match.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Infineon Technologies FM25CL64B-G is active and in production. The parts listed here are qualified equivalents if you need a second source or better availability.
The closest qualified second sources for the Infineon Technologies FM25CL64B-G are the MB85RS64VYPNF-G-BCE1 (RAMXEED) and the CY15B064Q-SXE (Infineon Technologies), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the FM25CL64B-G are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
