64 Mbit SPI Quad I/O NOR flash at 133 MHz
The S25FS064SAGBHV020 is a 64 Mbit serial NOR flash from the FS-S family, organized as 8M x 8 bits. Operating from a 1.7 V supply rail, this part fits low-voltage embedded designs where the core logic and I/O share a single 1.8 V domain.
Package and board integration
Housed in a 24-ball BGA package, the S25FS064SAGBHV020 requires a surface-mount reflow profile consistent with JEDEC MSL ratings for BGA devices. The 0.80 mm ball pitch and 6 x 8 mm body footprint fit a standard four-layer PCB fan-out without microvias. Supplied in tray packaging, this part is suited for production pick-and-place lines. The SPI Quad I/O interface uses six signal lines (CS#, SCK, SI/SIO0, SO/SIO1, WP#/SIO2, HOLD#/SIO3) plus the 1.7 V supply and ground.
