SF25C20 FRAM — Pin-to-Pin Compatible Replacement for Infineon (formerly Cypress) FM25V20A and Fujitsu MB85RS2MT
✅ Authorized Distributor of Smart Memories FRAM
📌 Direct, drop-in replacement — no PCB redesign required
-
Infineon (ex-Cypress) model: FM25V20A
Note: Cypress’s FRAM product line was fully integrated into Infineon following the acquisition.
→ SF25C20 is pin-to-pin (P2P) compatible with FM25V20A, enabling seamless hardware replacement.
-
Fujitsu model: MB85RS2MT
A classic 2-Mbit SPI FRAM widely adopted in industrial applications.
→ SF25C20 matches MB85RS2MT exactly in electrical characteristics, timing behavior, and SOP-8 package footprint.
