No wear-leveling needed: FRAM endurance is effectively unlimited compared to the 1M-cycle ceiling of serial EEPROM. For a data logger writing every 100 ms, that's the difference between a few days and the product's full service life. ## Supply rail and temperature grade Housed in the standard 8-SOIC narrow-body (5.30 mm width). Footprint matches countless existing SPI EEPROM and NOR flash layouts — no board respin for a drop-in FRAM swap.","metaTitle":"Infineon CY15B104Q-SXIT FRAM, 4Mbit SPI 40MHz 8-SOIC","metaDescription":"Infineon CY15B104Q-SXIT 4Mbit SPI FRAM, 40 MHz, 2V-3.6V, -40°C to 85°C, 8-SOIC.
