Product details

Cypress (now Infineon) no longer manufactures the S25FL164K0XBHI023 in the FL1-K series. No last-time-buy window exists; the part is already out of production.

108 MHz clock and Quad I/O — what the speed rating means

The 108 MHz clock frequency is the maximum SPI clock for Quad I/O reads. At that speed, the controller can fetch instructions or data at up to 54 MB/s (108 MHz × 4 bits). That is enough bandwidth to shadow-boot a 64 Mbit image in under 150 ms, or to stream firmware updates over the air without stalling the application. The 3 ms write cycle time per page (Word, Page) is typical for NOR — the controller must poll the status register or wait 3 ms before issuing the next write command. For OTA staging, plan a write buffer in the MCU RAM so the Flash write does not block the communication stack.

Frequently asked questions

Is S25FL164K0XBHI023 obsolete?

Yes, the S25FL164K0XBHI023 carries an Obsolete lifecycle status. Cypress (Infineon) no longer produces this part.

What is the replacement for S25FL164K0XBHI023?

No official replacement order code is recorded in the lifecycle data for the S25FL164K0XBHI023. There is no direct drop-in from the original manufacturer. For a pin-compatible alternative, evaluate other 64 Mbit NOR Flash devices in the 24-TBGA package with SPI Quad I/O support from vendors like Winbond or Macronix — but verify the footprint and command set against your firmware driver before committing the BOM.

Does S25FL164K0XBHI023 support SPI Quad I/O?

Yes, the memory interface is SPI Quad I/O. This allows four data lines for reads and writes, delivering higher throughput than standard single-line SPI at the same 108 MHz clock.
