FRAM writes are non-volatile and do not require a page-erase cycle like NOR flash. The write energy is lower, and the write endurance is effectively unlimited for field logging — no wear-leveling scheme needed at the application layer. No special reflow profile beyond the standard JEDEC level — rework with hot air is straightforward. ROHS3 compliant per the manufacturer's declaration.","metaTitle":"Infineon CY15B104QSN-108SXI FRAM, 4 Mbit, 108 MHz SPI","metaDescription":"Infineon CY15B104QSN-108SXI Excelon-Ultra FRAM, 4 Mbit, 108 MHz SPI Quad I/O, 1.8V-3.6V, -40°C to 85°C, 8-SOIC.
