512 Mbit NOR Flash in a parallel 64-FBGA package
The Infineon S29GL512T10FHI040 is a 512 Mbit parallel NOR Flash memory from the GL-T series, organized as 64M x 8 bits. It delivers a 100 ns access time and supports a supply range of 2.7 V to 3.6 V. The part is housed in a 64-ball FBGA (13x11 mm) and is rated for industrial temperature operation from -40°C to 85°C. This is a mainstream density and speed grade for code shadowing, configuration storage, and firmware updates in embedded systems — telecom line cards, motor drives, and industrial controllers that need a reliable parallel NOR with a straightforward interface.
100 ns access — what it means for bus timing
The 100 ns access time sets the read-cycle window the host controller must accommodate.
Industrial temperature range — deployment envelope
Rated -40°C to 85°C ambient, this is the industrial temperature grade.
Parallel interface — no SPI translation needed
This part uses a full parallel address/data bus, not a serial SPI or Quad-SPI interface. That means direct connection to the memory controller without protocol overhead — useful for legacy processor designs, FPGA configuration stores, or systems where the host already has a parallel NOR controller. The trade-off: more pins on the board (64-ball FBGA) compared to an 8-pin serial Flash, but with deterministic read latency and no command sequence overhead.
Lifecycle and sourcing
That means it remains a current-production part — no last-time-buy clock ticking, no NRND restrictions. For new BOM entries or ongoing production, this is a safe line item. The part is ROHS3 compliant.
