CY15B201QSN-108SXE

Active and preferred

The CY15B201QSN is a 1-Mb (128K × 8) automotive-grade ferroelectric RAM (F-RAM) with instant non-volatile writes, virtually unlimited endurance of 10 trillion cycles, and 121-year data retention. It operates from 1.8 V to 3.6 V across –40°C to +125°C, supporting Quad SPI and DDR interfaces up to 108 MHz. Integrated ECC and CRC ensure robust data integrity. AEC-Q100 Grade 1 and RoHS compliance make it ideal for frequent, reliable automotive and industrial data storage.
