CY15V104QI-20BFXIT

Active and preferred

The CY15V104QI-20BFXIT is a 4-Mbit EXCELON™ LP Ferroelectric RAM (F-RAM) with a 512K × 8 serial SPI interface. It operates at 1.71 V to 1.89 V and supports industrial temperatures from -40°C to +85°C. The device delivers 1015 read/write cycles and 151-year data retention at 60°C. With up to 20 MHz SPI clock, advanced write protection, and a dedicated 256-byte special sector, the 8-pin UFLGA package is RoHS compliant and ideal for reliable nonvolatile writes.
