They all feature one or two ARM Cortex-A9 CPU cores, as well as an 782c703feSHavard Skinnemoenassortment of peripherals targeted for either Enterprise or Data Center / 882c703feSHavard SkinnemoenHyperscale applications. The former is a superset of the latter, so NPCM750 has 982c703feSHavard Skinnemoenall the peripherals of NPCM730 and more. 1082c703feSHavard Skinnemoen 1182c703feSHavard Skinnemoen.. _Nuvoton iBMC: https://www.nuvoton.com/products/cloud-computing/ibmc/ 1282c703feSHavard Skinnemoen 13f548f201SPeter MaydellThe NPCM750 SoC has two Cortex-A9 cores and is targeted for the Enterprise 1482c703feSHavard Skinnemoensegment.
