Active 128 Mbit NOR Flash for code-shadowing and data-logging
The Infineon S25FL128SAGNFI011 is an active-production 128 Mbit FL-S series NOR Flash memory with an SPI Quad I/O interface clocked at 133 MHz. Organized as 16M x 8 bits, it operates from a 2.7 V to 3.6 V supply and is rated for the industrial temperature span of -40°C to 85°C.
Package and footprint considerations for the 8-WSON
Housed in an 8-WDFN exposed pad package (supplier device package 8-WSON 6x8 mm), the thermal pad must be soldered to a copper plane on the PCB to achieve the rated thermal performance. The exposed pad is the primary heat path; a via array under the pad to an inner-layer ground plane keeps junction temperature within the -40°C to 85°C operating range during sustained Quad I/O reads.
Lifecycle and supply posture for BOM planning
ROHS3 compliant, it ships in tube packaging — suitable for both prototype builds and production runs where reel quantities are not required.
