CY15V104QI-20BFXI

The CY15V104QI-20BFXI is a 4-Mbit EXCELON™ LP ferroelectric RAM (F-RAM) with high-speed SPI interface up to 20 MHz, optimized for industrial use. It operates from 1.71 V to 1.89 V and -40°C to +85°C, offering virtually unlimited endurance and 151-year data retention at 60°C. Low power modes, robust write protection, and unique device identification make it ideal for industrial control, data logging, and applications requiring reliable, rapid, nonvolatile writes.
