Memory interface and throughput
The S25FS512SDSNFB010: The Quad I/O SPI interface allows four data lines for read operations, quadrupling throughput over standard SPI without increasing the pin count. QPI mode extends this to command and address cycles as well, reducing protocol overhead. At 80 MHz, the effective read throughput reaches roughly 40 MB/s in Quad I/O — sufficient for fast boot sequences in automotive gateways or ADAS pre-load operations.
Housed in an 8-WSON package with exposed pad (supplier package 8-WSON 6x8 mm), this is a surface-mount part for reflow soldering.
The AEC-Q100 qualification means the part carries the full automotive PPAP documentation package.
