It organizes the memory as 8M x 8 bits and communicates over a SPI bus supporting Quad I/O and QPI protocols at a clock frequency up to 108 MHz, which gives read throughput adequate for execute-in-place (XIP) code shadowing and high-speed data logging. ## 108 MHz Quad SPI — what it buys the firmware engineer At 108 MHz in Quad I/O mode, the S25FL064LABNFA043 can sustain a read throughput that keeps a Cortex-M or Cortex-A core fed during code shadowing without stalling on flash access. The QPI mode reduces the command overhead by using the same four I/O lines for address and data, cutting the latency on random reads. If your bootloader or OTA staging area is sized for the 64 Mbit density, the 4 KB and 64 KB erase granularity matters when planning the wear-leveling and sector-map layout in the filesystem layer. The part comes in an 8-UDFN with exposed pad (supplier package designation 8-USON, 4x4 mm).","metaTitle":"S25FL064LABNFA043 64Mbit SPI NOR Flash, AEC-Q100, 108 MHz","metaDescription":"Infineon S25FL064LABNFA043 automotive-grade 64Mbit NOR Flash, SPI Quad I/O, 108 MHz clock, -40°C to 85°C, 8-UDFN.
