Unlike EEPROM, FRAM writes at bus speed with no page-buffer or erase cycle — each byte is written in a single SPI transaction, so the write time is deterministic and effectively zero for the host. Supply range is 2.7 V to 3.65 V, and the device is specified across the full industrial temperature band of -40°C to +85°C. The 8-SOIC package (3.90 mm body width) is a common footprint that drops into existing SPI memory sockets without board changes. ## Active production, ROHS3 — no last-time-buy pressure Infineon lists the FM25CL64B-GTR as Active with ROHS3 compliance. ## SPI bus timing and memory endurance — what the 20 MHz clock means At 20 MHz SPI clock, a full 64Kbit read or write completes in roughly 3.2 ms (ignoring command overhead). FRAM endurance is effectively unlimited for data-logging and parameter-storage applications — the write cycles are not wear-limited like flash or EEPROM, so the part can be written to continuously without tracking sector wear. ## Sourcing and availability — quoted to order This active FRAM is sourced through authorized and independent distribution channels. Pricing and lead time are confirmed at RFQ against your BOM quantity. No stock-holding claim is made; availability is verified per request.","metaTitle":"Infineon FM25CL64B-GTR FRAM, 64Kbit SPI 20MHz 8-SOIC","metaDescription":"Infineon FM25CL64B-GTR 64Kbit SPI FRAM, 8K x 8, 20 MHz, 2.7V-3.65V, -40°C to 85°C, 8-SOIC.
