512 Mbit parallel NOR flash for code execution
The S29GL512T11FHIV20 is an active-production 512 Mbit parallel NOR flash from Infineon's GL-T series, organized as 64M x 8 bits. Its 110 ns access time sets the read latency ceiling for direct code execution or shadowing to RAM — the parallel interface delivers sustained throughput without the serial overhead of SPI NOR parts.
Package and board integration
Housed in a 64-ball FBGA (13x11 mm) — the 0.80 mm ball pitch requires a 4-layer PCB for fan-out of the parallel address and data lines. The surface-mount footprint matches the standard GL-T series layout, so a board already routed for a 512 Mbit or 256 Mbit GL-T part needs no spin for this density.
