It uses an SPI interface with Quad I/O support, meaning it can transfer four bits per clock cycle, and is rated for a clock frequency of 104 MHz. That combination delivers read throughput sufficient for XiP (eXecute-in-Place) code storage in embedded systems where a separate RAM cache is not available. The memory is non-volatile NOR Flash, which provides fast random-read access and byte-rewrite capability, making it suitable for firmware storage, configuration data, and boot code in industrial and telecom equipment. The supply voltage range of 2.7V to 3.6V aligns with standard 3.3V logic rails. It comes in a 24-ball TBGA package measuring 8x6 mm (supplier device package 24-BGA). The Tape & Reel (TR) packaging is the shipping medium, not the device case. ## Write-cycle timing and endurance context Page write time is 3 ms typical, and word write time is 5 µs. These figures matter when sizing the firmware update window: a full 128 Mbit erase-and-write cycle takes longer than the page write suggests, because NOR Flash requires a sector erase before programming. Plan for the erase granularity when designing OTA or field-update routines.","metaTitle":"S25FL129P0XBHV203 128Mbit NOR Flash, Quad-SPI, 104 MHz","metaDescription":"Cypress S25FL129P0XBHV203 128Mbit NOR Flash, SPI - Quad I/O, 104 MHz clock, -40°C to 105°C, 24-TBGA.

A cross-reference search through distribution may identify a drop-in replacement."},{"question":"Is S25FL129P0XBHV203 compatible with SPI?","answer":"Yes, it uses a standard SPI interface with Quad I/O support. The memory interface is SPI - Quad I/O, meaning it is backward-compatible with single-bit SPI but can also operate in four-bit mode for higher throughput at the 104 MHz clock rate."},{"question":"Where to buy S25FL129P0XBHV203?","answer":"Because this part is obsolete, it is not available through authorized factory channels.
