The CY15B064Q-SXA is a 64-Kbit (8K × 8) automotive-grade serial F-RAM memory with SPI interface, providing nonvolatile storage and 100 trillion (1e14) read/write cycles. It operates from 2.7 V to 3.65 V, supports up to 20 MHz SPI clock, and ensures 151-year data retention at 65°C. NoDelay™ writes, low 200 μA active current at 1 MHz, and robust hardware and software write protection make it ideal for demanding automotive and industrial applications.
