256 Mbit parallel NOR for automotive XIP
The S26KS256SDABHM030 is a 256 Mbit parallel NOR flash from Infineon's HyperFlash KS family, organized 32M x 8 and accessed through a HyperBus interface at 100 MHz clock rate. The 1.7 V supply rail lets it share the 1.8 V nominal core domain common on automotive MCUs and SoCs, eliminating a dedicated regulator for the flash bank. The 96 ns initial access time from standby covers the random-read latency for code fetch; once in page mode, the DDR HyperBus delivers 166 MB/s sustained read bandwidth.
Package and board integration
Housed in a 24-ball FBGA (6x8 ball array, 0.80 mm pitch, 8x6 mm body), the part mounts on a standard surface-mount footprint. The bulk packaging means it ships in tray or tube — not tape-and-reel — so plan for manual or tray-fed pick-and-place rather than reel changeover. The parallel HyperBus interface uses a reduced pin count compared to traditional parallel NOR — address and data multiplexed on the same bus — so the board layout sees fewer traces between the flash and the host controller, simplifying routing on the 4- to 6-layer automotive PCB stack.
Sourced through authorized and independent distribution channels. The AEC-Q100 qualification and automotive-grade temp range make it a direct fit for production builds requiring traceable automotive flash.
Compliance and approvals
The part carries AEC-Q100 automotive qualification, covering the reliability stress, temperature cycling, and ESD sensitivity tests required for automotive-grade ICs. RoHS compliance is standard for Infineon's current NOR flash portfolio.
