Compact SiP For Datacenter Management

A new ultra-dense system-in-package is reshaping how AI servers and datacenters approach secure infrastructure. By fusing processing, memory, and power management into one chip, it eliminates design bottlenecks, accelerates development, and adds post-quantum protection for future-ready compute environments.

Nuvoton has rolled out the Arbel NPCM8mnx System-in-Package (SiP), a compact Baseboard Management Controller (BMC) subsystem aimed at addressing the rising demand for secure, scalable, and easily deployable infrastructure in the AI server and datacenter sectors. Launched at the OCP Global Summit, the new BMC SiP is designed to cut design complexity and slash deployment times for cloud compute platforms, putting a plug-and-play solution into the hands of hardware designers targeting next-generation workloads.​

It squeezes all necessary BMC hardware—CPU, memory, storage, reference clock, power management, and passive components—into a single 23x23mm BGA chip. With an estimated 70% reduction in subsystem footprint, this SiP targets dense computing nodes, from AI accelerators and multi-node compute cards to remote access modules and both edge and hyperscale datacenter deployments.

The key features are:

• Full Arbel NPCM8mnx BMC integration
• DDR4 memory: 1 GB–4 GB
• eMMC storage: up to 64 GB
• NOR Flash: up to 128 MB
• No high-speed signal simulations required
• Simplified power sequencing
• Enables faster hardware launches and more reliable systems
  

Security is a central focus. The product leverages the latest Arbel A3 architecture and features post-quantum cryptography (PQC) LMS algorithms for secure boot. It also offers DICE-based unique secret generation and supports custom key provisioning, aiming for compliance with emerging S.A.F.E. and FIPS 140-3 security requirements. Compatibility with OpenBMC, OP-TEE, U-Boot, Linux, and pRoT secure stacks ensures that the SiP can slot into open, industry-standard firmware environments with minimal friction.

For hardware architects and systems integrators, this launch signals a notable shift. Nuvoton’s ready-to-integrate BMC aims to accelerate engineering cycles for AI, cloud, and edge applications where space, speed, and security are make-or-break. Engineering samples are already available, with broad deployment likely to follow as the push toward distributed, AI-driven datacenters intensifies.
