CY15B004Q 4-Kbit Serial (SPI) Automotive F-RAM

Infineon Technologies CY15B004Q 4-Kbit Serial (SPI) Automotive F-RAM is a nonvolatile memory that uses an advanced ferroelectric process. Ferroelectric random access memory, or F-RAM, is nonvolatile and performs reads/writes similar to RAM. The CY15B004Q provides reliable data retention for 121 years while eliminating complexities, overhead, and system-level reliability problems caused by serial flash, EEPROM, and other nonvolatile memories.
