Infineon CY15B104QN-20BFXI

The EXCELON LP CY15X104QN is a low-power, 4-Megabit nonvolatile memory utilizing an advanced ferroelectric process. Ferroelectric RAM is nonvolatile and performs reads and writes similar to RAM. It eliminates the complexities, overhead, and system-level reliability issues of serial Flash, EEPROM, and other nonvolatile memories while delivering 151 years of reliable data retention. Unlike serial Flash and EEPROM, the CY15X104QN performs write operations at bus speed with no write delay. Data is written to the memory array immediately after each byte is successfully transferred to the device. The next bus cycle can begin immediately with no need for data polling. In addition, the device offers significantly higher write endurance than other nonvolatile memories. The CY15X104QN supports 10^15 read/write cycles — 1,000 million times more write cycles than EEPROM. These characteristics make it an ideal choice for nonvolatile memory applications requiring frequent or high-speed writes. The device employs a high-speed SPI bus, further enhancing the high-speed write capability of ferroelectric memory technology. It includes read-only device identification and ID functions, allowing the host to determine the manufacturer, product density, product revision, and the identification of each part. The device also provides a writable 8-byte serial number register that can be used to identify a specific board or system.
