The `Nuvoton iBMC`_ chips are a family of Arm-based SoCs that are
designed to be used as Baseboard Management Controllers (BMCs) in various
servers. They all feature one or two ARM Cortex-A9 CPU cores, as well as an
assortment of peripherals targeted for either Enterprise or Data Center /
Hyperscale applications. The former is a superset of the latter, so NPCM750 has
all the peripherals of NPCM730 and more.
servers. Currently there are two families: NPCM7XX series and
NPCM8XX series. NPCM7XX series feature one or two Arm Cortex-A9 CPU cores,
while NPCM8XX feature 4 Arm Cortex-A35 CPU cores. Both series contain a
different assortment of peripherals targeted for either Enterprise or Data
Center / Hyperscale applications.
