256 Mbit NOR Flash with Quad I/O — what it is and where it fits
The Cypress S25FL256SDSBHV210 is a 256 Mbit NOR Flash memory from the FL-S series, organized as 32M x 8 bits. It uses an SPI Quad I/O interface running at 80 MHz, which allows fast read throughput for code shadowing or execute-in-place in embedded systems. The 2.7 V to 3.6 V supply and -40 °C to 105 °C operating temperature range suit it for industrial control, outdoor telecom, and automotive under-hood environments where the board sees extended temperature cycling.
80 MHz clock and Quad I/O — what it means for the bus
The 80 MHz SPI clock with Quad I/O provides a raw read throughput suitable for boot or firmware updates without a parallel NOR interface.
Industrial temperature grade — deployment context
Rated for -40 °C to 105 °C, this part handles the thermal swing in a motor drive cabinet or a base-station radio head. The 24-TBGA (8x6 mm) package keeps the board footprint small, but the BGA requires controlled reflow and X-ray inspection — not a hand-solder part for prototype rework.
Lifecycle and sourcing reality
This part carries an EOL lifecycle stage. Sourcing moves to the independent distribution channel; availability and pricing are confirmed at quote time.
