What this 2 Gbit automotive NOR Flash brings to the BOM
The MT25QL02GCBB8E12-0AAT is a 2 Gbit NOR Flash qualified to AEC-Q100. It stores non-volatile code across a 256M x 8 organization, accessed via SPI Quad I/O at 133 MHz.
133 MHz SPI Quad I/O — what it means for boot time
The write cycle times — 8 ms for a page program, 2.8 ms for a word program — are typical for this process node and not a bottleneck for field-update scenarios. The real performance lever is the read side, and 133 MHz Quad I/O is the headline figure that determines whether this part fits the timing closure of your boot sequence.
