The Cypress S25FL164K0XBHV033 is a 64 Mbit NOR Flash memory organized as 8M x 8 bits, accessed through an SPI Quad I/O interface running at 108 MHz. This Quad I/O capability allows the device to shift four data bits per clock cycle, delivering read throughput that can keep up with a Cortex-M or similar MCU's code shadowing or data logging needs without waiting on a narrow serial bus.
Temperature grade and package — where it fits the board
Surface-mount assembly is standard, but the BGA footprint means rework is more involved than a SOIC or QFP.
The S25FL164K0XBHV033 is officially Obsolete. Cypress (now Infineon) has ended production, and no last-time-buy window remains open. Availability is intermittent and pricing reflects scarcity — not a standard distribution line.
Sourcing this part now
Because the S25FL164K0XBHV033 is obsolete, it is not stocked in standard distribution. We source it through our independent supply network — each unit is verified against the original Cypress datasheet and tested for functionality before shipment.
