Cypress Infineon 256Kbit FRAM NVRAM, SPI, SOIC

The Cypress Infineon 256Kbit FRAM NVRAM is an advanced Ferroelectric Random Access Memory device, packaged in an 8-pin SOIC format. With a memory configuration of 32K x 8bit, this non-volatile memory reads and writes similarly to RAM, providing reliable data retention for 151 years. It eliminates the complexities, overhead, and system-level reliability problems often caused by serial flash, EEPROM, and other non-volatile memories.

Unlike serial flash and EEPROM, this FRAM performs write operations at bus speed without incurring write delays. Data is written to the memory array immediately after each byte is successfully transferred, allowing the next bus cycle to commence without the need for data polling. Additionally, the device offers substantial write endurance compared to other non-volatile memories, serving as a direct hardware drop-in replacement for users of serial EEPROM or flash.
