512 Mbit parallel NOR for automotive XIP and code-shadowing
The Infineon S26KS512SDPBHM020 is a 512 Mbit parallel NOR flash from the Automotive, AEC-Q100 HyperFlash KS family. It clocks at 166 MHz and delivers a 96 ns initial access time, optimized for execute-in-place (XIP) boot and real-time code execution in automotive ECUs, ADAS, and infotainment domains. Packaged in a 24-FBGA (6x8 mm), it uses a parallel interface organized as 64M x 8 bits.
The 166 MHz clock rate governs the synchronous burst read throughput — critical for feeding a high-speed MCU or SoC without wait-state penalties. The 96 ns random access time sets the initial latency for the first word after a new address; subsequent words in the burst arrive at the clock rate. For a system that boots from NOR and runs code in place, these two numbers together define the memory wall. At 1.7 V the timing margins shrink — verify signal integrity against the controller's input hold times at the low end of the supply range.
AEC-Q100 qualification and the 125°C operating ceiling
That means it is characterized and reliability-tested for engine bay, transmission, and high-ambient interior modules. No last-time-buy math needed for a new design-in.
Package and footprint: 24-FBGA (6x8 mm)
Surface-mount only. The tray shipping medium means parts arrive in antistatic trays, not tape-and-reel.
