64 Mbit automotive NOR flash with Quad SPI at 108 MHz
The S25FL064LABBHB023 is a 64 Mbit (8M x 8) NOR flash from Infineon's FL-L series, qualified to AEC-Q100 for automotive applications.
Temperature range and supply voltage
The supply range is 2.7V to 3.6V, covering the standard 3.3V rail with margin for transients on an automotive power bus.
Housed in a 24-TBGA (8x6 mm body), the 0.80 mm ball pitch demands a 4-layer PCB for clean fan-out — two-layer boards will struggle to route all signals without vias under the package.
For volume BOM planning, this part is a single-source gate — there is no official second-source pin-compatible drop-in from another vendor, so the supply chain depends on Infineon's fab capacity.
