It uses a standard SPI interface with Quad I/O and QPI support, allowing read throughput up to 108 MHz clock frequency. Typical applications include firmware storage, boot code, parameter logging, and over-the-air update staging in embedded systems such as industrial controllers, networking gear, IoT edge nodes, and automotive infotainment or telematics units. The 108 MHz clock rate on the SPI bus, combined with Quad I/O, delivers a sustained read bandwidth that can keep a Cortex-M or similar core fed without wait states during XIP (eXecute In Place) operation. At this speed, the flash can saturate a 50 MHz Quad-SPI controller with margin. The QPI mode reduces command overhead by using all four I/O lines for both address and data, cutting latency on random reads. For designs that boot from external flash, this clock speed directly impacts startup time and real-time response. The 8-UDFN package with exposed pad (supplier package 8-USON 4x4 mm) keeps the board footprint small — about the size of an SOIC-8 but thinner — and the pad helps pull heat out during sustained read bursts. Surface-mount assembly is straightforward with standard reflow profiles.","metaTitle":"S25FL064LABNFV043 64Mbit SPI NOR Flash, 108 MHz, Active","metaDescription":"Cypress S25FL064LABNFV043 64Mbit SPI NOR Flash in 8-UDFN package. 108 MHz clock, Quad I/O, -40 to 105°C.
