Product details

256 Mbit NOR flash — firmware and data-logging density

The S25FL256SAGMFV003 is a 256 Mbit NOR flash from Infineon's FL-S series, organized as 32M x 8 and accessed through an SPI Quad I/O interface at up to 133 MHz. The 256 Mbit density suits firmware images that exceed 16 MB, plus a data-logging partition, without needing a second device on the bus.

Industrial temperature range and supply rail

The -40°C to 105°C ambient range covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary modules — the 105°C ceiling keeps data integrity during a stalled fan or summer heat soak. The 16-SOIC wide-body package (7.50 mm body width) is a rework-friendly footprint — standard hot-air stations handle it without a preheater, and the 1.27 mm pitch allows two-layer PCB breakout. The supplier device package is listed as 16-SOIC, matching the 16-SOIC (0.295", 7.50mm Width) case code.

Frequently asked questions

What is the clock frequency and interface of S25FL256SAGMFV003?

The S25FL256SAGMFV003 supports SPI Quad I/O at a clock frequency of 133 MHz. Quad I/O mode reads four bits per clock cycle, delivering a sustained throughput that keeps a Cortex-M4 or RISC-V core fed during XIP execution without wait-state stalling.

What temperature range does S25FL256SAGMFV003 support?

This industrial-grade rating means the flash retains data and meets timing over the full automotive cabin and engine-bay auxiliary module envelope — no derating needed for a 95°C enclosure interior.
