128 Mbit SPI NOR Flash with quad-I/O read
The S25FL129P0XNFI003: This is a 128 Mbit (16 M x 8) NOR Flash memory organized in a single non-volatile array, accessed over an SPI bus with Quad I/O support for faster read throughput. The clock frequency reaches 104 MHz, and with quad-I/O read the effective data rate can approach 416 Mbps — useful for code shadowing or high-speed firmware updates.
Package and temperature grade
Housed in an 8-WDFN exposed-pad package (8-WSON 6x8 mm), the part is surface-mount with a thermal pad that should be soldered to a PCB copper plane for heat dissipation. Rated for industrial temperature range -40°C to +85°C, it suits outdoor telecom, factory automation, and other ambient-controlled enclosures.
