Ambiq Micro, Inc. ("Ambiq®") , a leader in ultra-low-power semiconductor solutions for edge AI, today revealed new technical details of its upcoming Atomiq™ SoC. Built on Ambiq's newly designed 12nm SPOT® platform using the TSMC N12e® process, Atomiq introduces a new Ultra-Low-Power (ULP) mode engineered to operate as low as 300mV— the lowest operating voltage in Ambiq's history.
This announcement marks the first planned deployment of SPOT on a FinFET node and reflects continued progress toward initial Atomiq110 samples, with production scheduled for 2027.
FinFET + SPOT: Unlocking a New Power Frontier
By combining Ambiq’s proprietary subthreshold design methodology with TSMC’s advanced 12nm FinFET process, Atomiq enables high-speed sub- and near-threshold performance that was previously impractical in planar CMOS processes.
The new ULP mode targets operation at voltages as low as 300mV while maintaining effective performance, expanding dynamic range across Ultra-Low-Power (ULP), Low-Power (LP), and High-Performance (HP) modes. This advancement positions Ambiq to deliver its lowest operating voltage and highest energy efficiency to date.
Purpose-Built for Edge AI
Atomiq is optimized for AI workloads, which scale efficiently through parallel processing rather than raw clock speed. The previously announced Arm® Ethos™-U85 NPU executes hundreds of multiply-accumulate (MAC) operations simultaneously, delivering tens of billions of operations per second even in ULP mode with clock speeds as low as 100 MHz.
Running inference in ULP mode near 300mV is expected to significantly reduce energy consumption for edge AI applications while using standard development tools and ecosystems. This ultra-low-power feature supports the SoC's subsystems, including the processor, NPU, and multimedia engines.
Platform Innovation Enabling Ultra-Low-Power Operation
Achieving operation down to 300 mV required significant architectural innovation. Atomiq incorporates a redesigned on-chip power management unit with a highly configurable, multi-channel Single-Inductor Multiple-Output (SIMO) buck converter. This adaptive power system dynamically adjusts to variations in process, temperature, and workload, delivering six independent voltage rails across load ranges spanning from nanoamps to milliamps.
Achieving such aggressive voltage scaling also required development of new custom foundation IP engineered for reliable ultra-low-voltage operation. The 12nm SPOT platform has been validated on silicon in Ambiq’s labs, marking a significant technical milestone toward commercializing Atomiq.
