The CY15E004J-SXAT is a 4-Kbit (512 × 8) automotive-grade serial F-RAM with an I2C interface, operating from 4.5 V to 5.5 V and supporting bus speeds up to 1 MHz. It offers 100 trillion (1e14) read/write cycles, 151-year data retention at 65°C, and NoDelay™ writes for real-time performance. With low power consumption and robust data integrity, it is ideal for nonvolatile memory applications requiring frequent, rapid writes in automotive environments.
