1 Gbit parallel NOR — the code-storage workhorse
The S29GL01GT10FHI020 is a 1 Gbit parallel NOR flash from the GL-T series, organized as 128M x 8 bits. It uses a parallel memory interface with a 100 ns random access time, which means the CPU can read instructions directly from the flash without copying to RAM first — the classic execute-in-place (XIP) boot path for embedded systems that need fast, deterministic code fetch. The write cycle time — word or page — is 60 ns, so page programming completes quickly once the data is buffered.
Industrial temp and BGA package — bench-fit reality
The part ships in tray packaging — typical for BGA devices that go through pick-and-place in volume. No reel or tape option is listed, so the tray is the only confirmed carrier.
For BOM risk management, the closest peer in the same GL-T family is the S29GL512T11TFIV20 — 512 Mbit density, same 64-FBGA package, same parallel interface, same industrial temp range. If the application can halve the code storage, that part drops into the same footprint without a board spin.
