AEC-Q100 NOR Flash for automotive code storage
The S25FL064LABNFA011: Non-volatile array organized as 8M x 8 bits, accessed through SPI Quad I/O and QPI at 108 MHz.
108 MHz Quad SPI — throughput for fast boot and OTA
With a 108 MHz clock and Quad I/O interface, this part delivers read throughput suitable for execute-in-place (XIP) code shadowing and over-the-air update staging. The QPI mode reduces command overhead by using all four I/O lines for both address and data, which matters when the MCU is fetching from external Flash at speed. For a firmware bring-up engineer: the 108 MHz PLL in the host controller needs the correct dummy-cycle setting in the read command sequence; the datasheet's AC timing table gives the setup and hold margins for that negotiation.
Surface-mount part in an 8-WSON (5x6 mm) with exposed pad for reflow assembly.
The FL-L series has broad distribution coverage, so multi-source availability is typical through independent and franchised channels.
