Product details

Obsolete — sourcing the S25FL129P0XNFV003 for your BOM

The memory is non-volatile, with a write cycle time of 5 µs per word and 3 ms per page. It is supplied in an 8-WDFN exposed pad package (also designated 8-WSON, 6x8 mm), surface-mount only.

What the 104 MHz Quad I/O means for your design

The 104 MHz clock rate with Quad I/O effectively quadruples the read bandwidth compared to a single-bit SPI at the same frequency, which is critical for fast boot times and reducing the latency of firmware updates over the air. The 128 Mbit density (16 MB) is a common sweet spot for storing a bootloader, kernel, and a small filesystem in a single NOR flash device, avoiding the need for a separate NAND controller.

Frequently asked questions
