What this part is and where it fits
The Infineon S29GL512S12DHE010 is a 512 Mbit parallel NOR Flash from the GL-S series, qualified to AEC-Q100 for automotive applications. It uses a CFI (Common Flash Interface) parallel bus, organized as 64M x 8 bits, and operates from a single 2.7 V supply. The 120 ns access time supports execute-in-place (XIP) code execution for the host microcontroller or SoC without needing to shadow code into RAM. The -55°C to 125°C temperature range covers under-hood automotive, avionics, and other harsh environments where standard commercial parts cannot survive.
120 ns access time — what it means for the bus
The 120 ns access time is the random-read latency for the parallel bus. The memory is organized as 64M x 8 bits.
Lifecycle and sourcing posture
The S29GL512S12DHE010 is listed as Active in production — no last-time-buy or end-of-life notice is currently in effect. For current BOMs, this means no forced redesign cycle. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.
How it compares to the serial SPI peer S25FL512SAGMFBG10
The S25FL512SAGMFBG10 is a 512 Mbit automotive NOR Flash with a serial SPI (Quad I/O) interface. It has a -40°C to 105°C temperature range.
