512 Mbit NOR Flash for execute-in-place and firmware storage
It communicates over a SPI bus with Quad I/O and QPI protocol support, clocked at 133 MHz. The 1.7 V supply and industrial temperature range from -40°C to 105°C suit it for outdoor telecom basestations, automotive engine-control modules, and factory-automation controllers that need reliable code storage and execute-in-place performance. The 512 Mbit density holds multiple firmware images for over-the-air update schemes or large lookup tables for motor-drive profiles.
133 MHz Quad SPI — read bandwidth for XIP
At 133 MHz in Quad I/O mode, the S25FS512SAGMFV010J delivers sustained read throughput that keeps a Cortex-M7 or similar core fed during execute-in-place without wait states on cache misses. The QPI mode reduces the command sequence to a single byte, cutting overhead on narrow MCU buses. Compared to the 256 Mbit MT25QU256ABA1EW7-0SIT, this part doubles the density at the same 133 MHz clock and 1.7 V supply, but the Micron peer is rated to 85°C only — the Cypress part holds the full 105°C industrial grade.
That means Cypress continues to produce this order code with no announced last-time-buy window. For production planning, this removes the obsolescence risk that haunts older NOR Flash densities.
Industrial temperature grade — 105°C for harsh environments
The 1.7 V supply aligns with low-voltage SoC rails.
