Infineon/CYPRESS CY15B116QSN-108BKXI

The EXCELON Ultra CY15x116QSN is a 16Mb nonvolatile memory device built on an advanced ferroelectric process. Ferroelectric RAM is nonvolatile and performs reads and writes like RAM. It delivers reliable data retention while eliminating the complexity, overhead, and system-level reliability concerns associated with serial Flash and other nonvolatile memories. Unlike serial Flash, the CY15x116QSN executes write operations at bus speed with no write delays. Data is written to the memory array immediately upon successful transfer to the device, enabling the next bus cycle to begin without data polling. In addition, the device offers significantly higher write endurance than other nonvolatile memories. The CY15x116QSN supports an extremely high number of read and write cycles. These characteristics make it well suited for nonvolatile memory applications requiring frequent or high-speed writes. The CY15x116QSN combines 16Mb F-RAM with a high-speed quad-wire SPI interface, enhancing the nonvolatile write capability of ferroelectric memory technology. The device includes read-only device identification and ID features that allow the SPI bus master to determine the manufacturer, product density, product revision, and the ID of each unit. The device also provides a read-only serial number that can be used to identify a board or system. The device supports on-chip ECC logic capable of detecting and correcting 2-bit errors within every 8-byte unit of data. It further extends this capability to report 3-bit errors within an 8-byte data unit. The CY15x116QSN also supports a CRC function that can be used to verify the integrity of data in the memory array.
