Amlogic has unveiled the A123X quad-core and C305X2 dual-core Arm Cortex-A320 SoCs for industrial and battery-powered Edge AI and IoT applications. The company is the first silicon vendor to announce Cortex-A320 SoCs, and both processors are now in sampling with mass production scheduled for Q4 2026.
The Arm Cortex-A320 low-power Armv9 CPU core was introduced in February 2025, and Amlogic's early adoption marks a significant milestone for the low-power edge processing ecosystem. Details are still sparse — no full specifications or block diagrams have been published, and software information is limited — but the target applications are clear.
A123X: machine vision for industrial applications
The A123X is designed for machine vision industrial applications such as dashcams, sweeping robots, access control, and video conferencing hardware. As a quad-core Cortex-A320 SoC, it targets applications that need respectable multi-core throughput for on-device vision processing while keeping power consumption low enough for always-on deployment.
C305X2: ultra-low-power battery devices
The C305X2 is optimized for ultra-low-power battery devices such as solar doorbells, portable hunting cameras, and compact 2K/4K battery IP cameras. It looks to be an upgrade to the C305X dual-core Cortex-A35 SoC, bringing the newer Cortex-A320 core's efficiency and Armv9 features to battery-powered edge devices.
Software and ecosystem
On the software side, Amlogic says the A123X and C305X2 processors leverage Cortex-A320's Linux software compatibility — a key selling point for developers who want a familiar toolchain. The company will also offer turnkey reference designs, pre-validated embedded OS stacks, and unified NN SDKs.
While the full SDK has not been released publicly, a few C305X2 references show up on the Amlogic-NN GitHub account, suggesting the neural network tooling is already in early circulation for beta customers.
Why Cortex-A320 matters
The Cortex-A320 is Arm's most affordable entry into the Armv9 ecosystem, designed for deeply embedded and low-power applications. It brings pointer authentication and other Armv9 security features to devices that previously used Cortex-A35 or older cores. For IoT and edge AI, that means a upgrade path that preserves Linux compatibility while adding modern security and efficiency.
Amlogic's move to ship the first Cortex-A320 SoCs signals that the low-power edge AI market is ready for a new generation of chips — one that balances the needs of machine vision, battery life, and cost in a single platform. If mass production lands on schedule in Q4 2026, these SoCs could power a wave of smarter, more capable IoT devices by early 2027.
