32 Mbit SPI NOR Flash for firmware storage
The Cypress S25FL032P0XNFV000 is a 32 Mbit SPI NOR Flash memory from the FL-P series, organized as 4M x 8 bits and accessed through a Quad I/O SPI interface at up to 104 MHz. The part is housed in an 8-WDFN exposed pad package (6x8 mm WSON), which provides a low-profile footprint for space-constrained PCBs.
This device carries an Obsolete lifecycle status. Buyers should evaluate pin-compatible alternatives in the FL-P family for new designs, as the 8-WSON footprint and Quad I/O interface are common across the series, though each density variant requires its own code verification.
Write-cycle timing and page erase granularity
The memory supports a page write cycle time of 3 ms and a word write time of 5 µs. These timings matter for OTA staging and configuration storage: the 64 KB sector erase granularity (typical for NOR Flash of this density) influences the firmware update strategy, especially when wear-leveling is implemented in the filesystem layer. For designs that require frequent field-reprogramming, the endurance rating (not listed on this record but standard for the FL-P family at 100k cycles per sector) should be confirmed against the product's service life.
