Features ultra-low-power BLE 6.3 with in-line PCT Channel Sounding for high-accuracy distance measurement while delivering industry-leading battery longevity

Atmosic Technologies, Inc., a pioneer in ultra-low-power wireless connectivity and compute solutions, today announced the availability of its ATM53 series Bluetooth System-on-Chip (SoC). Designed to set a new benchmark in energy efficiency, the ATM53 integrates Bluetooth 6.3 channel sounding with in-line Phase Correction Term (IPT), enabling unmatched battery life for distance-measurement applications across consumer and enterprise markets.

Key Technical Highlights

• Next-Gen Location Accuracy: Integrates in-line PCT channel sounding—aligned with the latest iOS and Android operating system specifications—to provide distance measurement for consumer tags and enterprise asset management.
• Sensing Layer for Physical AI: A smart, secure aggregation node combining compute, BLE connectivity, and multi-sensor interface, all at ultra-low power.
• Industry-Leading Battery Longevity: Combines Atmosic’s ultra-low-power compute architecture with optimized RF performance and a dedicated hardware accelerator for in-line PCT channel sounding for unparalleled efficiency.
• Robust Hardware Specs: Powered by an ARM® Cortex®-M33F core, equipped with 512KB ROM, 256KB RAM, up to 2MB non-volatile memory and 48 GPIOs.
• Unified Platform Architecture: Complemented by the footprint-compatible ATM52 (a BLE 5.4 variant without channel sounding), allowing OEMs to deploy multi-tiered product lines off a single PCB design.

"To meet the surging demand for Physical AI and modern location services, the ATM53 delivers high-accuracy channel sounding without sacrificing energy efficiency," said Ali Foughi, CEO of Atmosic. "By pairing in-line PCT processing with our signature ultra-low-power architecture, we are delivering yet another industry leading solution to empower Physical AI development teams to build intelligent, long-lasting tracking solutions."
