256 Mbit SPI NOR Flash — density, interface, and the timing budget
The S25FL256SAGMFIR13 is a 256 Mbit SPI NOR flash from Infineon's FL-S series, organized as 32M x 8 bits. The 133 MHz clock rate combined with the Quad I/O interface delivers a burst read throughput of 532 Mbit/s (four data lanes at 133 MHz) — enough for code-shadowing and execute-in-place (XIP) in most embedded controllers that support a QSPI peripheral. The 2.7 V minimum sets the brownout floor — the system supply must stay above this during read, program, and erase cycles, or the device may latch or corrupt the memory array. The industrial temperature range (-40°C to +85°C) qualifies this part for factory-floor automation, outdoor telecom enclosures, and HVAC controllers. It is not rated for under-hood automotive (125°C) or extended industrial (105°C) without selecting a different temperature-grade variant from the FL-S family.
Package and board-fit — 16-SOIC wide-body footprint
The 16-SOIC package has a 0.295-inch (7.50 mm) body width and a 1.27 mm pin pitch — a standard wide-body SOIC footprint that routes easily on a two-layer board. The supplier device package is listed as 16-SOIC, matching the package / case field. Surface-mount assembly with Tape & Reel (TR) packaging — the reel quantity is set by the distributor's stock-keeping unit; confirm the reel size (standard 13-inch or 7-inch) at RFQ time.
