FFF CompatibilityPinout matches the standard SPI F-RAM pin sequence on an 8-pin SOIC layout.Utilizes a compatible 8-SOP/SOIC package footprint.Operates within an equivalent frequency, temperature, and voltage ceiling.The pinout has been verified as identical to the queried part: Pin 1 (CS), Pin 2 (SO), Pin 3 (WP), Pin 4 (VSS), Pin 5 (SI), Pin 6 (SCK), Pin 7 (HOLD), Pin 8 (VDD).Uses the same standard 8-pin SOIC (150 mils) physical package and dimensions.Operating voltage range is narrower (3.0 V to 3.6 V vs. 2.7 V to 3.65 V) and maximum clock frequency is lower (16 MHz vs. 20 MHz) compared to the queried part.
AI Summary

FM25CL64B-G by Infineon Technologies: FRAM (Ferroelectric RAM) Memory IC 64Kbit SPI 20 MHz 8-SOIC.

This is a second-source 64-Kbit SPI F-RAM from RAMXEED (formerly Fujitsu) that serves as a direct functional equivalent. It matches the 20 MHz clock speed and operating temperature parameters, but note that this part is classified as Not For New Designs.

  • Matches the 20 MHz maximum SPI clock frequency of the original
  • Fully compatible 2.7V to 3.6V operating range
  • Matching 64-Kbit (8K x 8) organization
  • Part is classified as Not For New Designs (NFND) by the manufacturer

This is a sibling automotive-grade 64-Kbit serial SPI F-RAM offering identical pinout and physical package parameters. However, it operates with a narrower voltage range of 3.0 V to 3.6 V and a slightly reduced maximum SPI clock speed of 16 MHz.

  • Pin-compatible drop-in replacement in 8-pin SOIC package
  • Automotive-grade reliability (AEC-Q100 Grade 1)
  • Extended operating temperature range: -40°C to +125°C (vs. -40°C to +85°C)
  • Narrower operating voltage range: 3.0 V to 3.6 V vs. 2.7 V to 3.65 V
  • Lower maximum clock frequency: 16 MHz vs. 20 MHz

You searched one part. Parter watches your whole BOM.

  1. 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.

  2. 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.

  3. 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.
