512 Mbit NOR Flash with AEC-Q100 qualification for automotive and industrial
The S25FS512SDSBHM210: It uses a SPI interface with Quad I/O and QPI support, clocked at 80 MHz.
80 MHz Quad-SPI — throughput for firmware and data logging
The 80 MHz clock frequency with Quad I/O and QPI modes delivers read throughput that keeps the host processor fed during code shadowing or data-logging bursts.
1.7V to 2V supply — single-cell Li-ion or 1.8V rail operation
The supply voltage range of 1.7V to 2V allows the part to run directly from a single Li-ion cell (nominal 3.6V stepped down to 1.8V) or a regulated 1.8V rail. Designers should verify that the host controller's SPI I/O levels are compatible with the 1.8V domain, or add level shifters if the controller runs at 3.3V.
