512 Mbit parallel NOR Flash — what the 110 ns access time means for your bus
The Cypress S29GL512T11TFV020 is a 512 Mbit parallel NOR Flash memory from the GL-T series, organized as 64M x 8 bits. That 110 ns figure sets the read cycle window for the host controller — at this speed, the Flash can keep up with a moderate-speed MCU or FPGA without wait states, but a fast 32-bit processor running above 50 MHz will need to insert a few wait cycles on the external bus.
Industrial temperature range — why 105°C matters
That extra 20°C headroom above 85°C is critical for designs that sit near a hot processor, inside a sealed enclosure with no airflow, or on a board that shares a heatsink with a power stage.
Active lifecycle — no end-of-life surprises
The GL-T series is a mature, well-established NOR Flash family, so PCNs are infrequent and typically minor (wafer fab or test-site changes). If you are qualifying this for a new design, the active status gives you a multi-year sourcing window without the risk of an abrupt EOL.
Package and footprint — 56-TSOP handling notes
The 56-TSOP package (0.724" body width, 18.40 mm) is a standard thin small-outline package for NOR Flash. It is surface-mount only, so the reflow profile should follow the JEDEC standard for TSOPs. If the reel has been open longer than that, a bake at 125°C for 24 hours is recommended before reflow to prevent popcorning.
