What this GL-S NOR Flash brings to the board
The Infineon S29GL128S90DHI010 is a 128 Mbit parallel NOR Flash from the GL-S family, organised as 8M x 16 bits. It runs on a 2.7 V to 3.6 V supply and delivers a 90 ns access time — fast enough for most 16-bit microcontroller or FPGA configuration buses without a wait-state penalty. The 64-FBGA (9x9 mm) package keeps the footprint small, and the -40°C to 85°C industrial temperature range means it can sit in outdoor telecom cabinets or factory-floor controllers without derating concerns.
90 ns access time — what it buys you on the bus
A 90 ns random-access read suits a 16-bit wide memory. The 60 ns write cycle time (word/page) keeps firmware-update windows short.
