128 Mbit Quad SPI NOR flash — what it does
The Infineon S25FL129P0XBHIZ13 is a 128 Mbit NOR flash memory from the FL-P series, organized 16M × 8 and accessed through a Quad SPI interface clocked at 104 MHz. It operates on a 2.7 V to 3.6 V supply and is rated for -40 to 85 °C industrial temperature range. The 24-TBGA (8×6 mm) footprint suits compact embedded designs where code shadowing or data logging demands fast read throughput from a non-volatile store.
104 MHz Quad SPI — what the clock rating means for the design
The 104 MHz clock frequency on the Quad SPI interface delivers read throughput sufficient for execute-in-place (XIP) code shadowing or high-speed firmware updates. For a design already locked to this FL-P series footprint, the Quad I/O mode reduces pin count versus a parallel NOR flash, saving board area on the 24-ball BGA. If your system can tolerate a slower read rate, a single-SPI NOR flash in the same density would free up three I/O lines, but the Quad interface is the faster path for latency-sensitive boot sequences.
The 24-TBGA (8×6 mm) package is a fine-pitch BGA requiring controlled solder-profile reflow and X-ray inspection for voiding. Storage temperature exceeds the operating range, so the part can survive the reflow cycle and handling between builds.
