It comes in a 24-BGA (8x6 mm) package, surface-mount only. ## 66 MHz Quad SPI — bus margin and boot time The 66 MHz clock rate with Quad I/O gives a theoretical read throughput around 33 MB/s. That is fast enough for shadowing code to RAM or staging OTA firmware updates without stalling the host controller. The QPI mode cuts the command overhead by using a 4-bit serial bus for both address and data, which tightens the latency for random-read workloads. ## 24-BGA footprint — rework and layout notes The 8x6 mm body fits on a standard four-layer PCB with via-in-pad if the layout is tight.","metaTitle":"S25FL128LDPBHI020 128Mbit NOR Flash, 66 MHz Quad SPI, 24-BGA","metaDescription":"S25FL128LDPBHI020 128Mbit FLASH - NOR, SPI - Quad I/O, QPI, 66 MHz clock, 2.7V-3.6V, -40°C to 85°C, 24-BGA.
