Reliable 2048kBit SPI FRAM with 20MHz frequency, Automotive(E) qualification, and wide operating temperature range of -40°C to 125°C. The CY15B102Q-SXE is a 2-Mbit (256 K × 8) automotive-grade serial F-RAM with 10 trillion read/write cycles and 121-year data retention at 85°C. Operating from 2.0 V to 3.6 V, it supports SPI speeds up to 25 MHz. No write delays and low power consumption (5 mA active, 750 μA standby, 20 μA sleep) make it ideal for frequent, rapid-write automotive and industrial applications. Hardware and software write protection and AEC-Q100 Grade 1 compliance ensure robust reliability.
