INFINEON CY15E004Q-SXE Ferroelectric RAM, 4 Kbit, SPI, 16 MHz, 4.5 V to 5.5 V Supply, SOIC-8 SP005650541, CY15E004Q-SXE

CY15E004Q-SXE is a CY15E004Q 4Kbit non-volatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is non-volatile and performs reads and writes similar to a RAM. It provides reliable data retention for 121 years while eliminating the complexities, overhead, and system level reliability problems caused by serial flash, EEPROM and other non-volatile memories. It is ideal for non-volatile memory applications requiring frequent or rapid writes. Examples range from data collection, where the number of write cycles may be critical, to demanding industrial controls where the long write time of serial flash or EEPROM can cause data loss. It provides substantial benefits to users of serial EEPROM or flash as a hardware drop-in replacement. This uses the high-speed SPI bus, which enhances the high-speed write capability of F-RAM technology.
