Ambiq powers chiplet for AI smart ring
Ambiq is working with Bravechip Technology in China on an AI chiplet for smart ring designs.
The Bravechip Artificial Intelligence of Things (AIoT) System in a Package (SIP) and printed circuit board assembly (PCBA), for the BCL603S3L chiplet uses the Ambiq Apollo3 Blue sub-threshold microcontroller.
The BCL603S3L is a high-performance, ultra-low power chiplet with the Apollo3 Blue as its master control, optimizing the CPU to achieve 6 uA/MHZ power levels. The sub-threshold design significantly decreases active power consumption for a range of tasks such as heart rate, blood oxygen, blood pressure, sleep, step counting, 3DoF, 6DoF, and other applications.

The Ambiq Apollo 3 is already used in a smart ring from Noise in India.
Founded at the end of 2018, Bravechip Technology packages multiple bare dies together through advanced packaging to provide chip-level solutions for downstream users
The Bravechip products can be widely used in narrowband IoT scenarios with tens of billions of connections such as medical, industrial, and home. The company taps into Tsinghua University School of Integrated Circuits and Nanjing Linkwah Institute of Integrated Circuit Technology.
The Apollo3 Blue SoC comes with BLE 5.2, embedded low-power Bluetooth protocol stacks, and GATT services connecting smart rings to smartphones. Integrating the Apollo3 Blue also allows for a more compact design with a 4 x 6.8mm LGA package, enabling Smart Ring manufacturers to design with a two-layer FPC board. This reduces the number of components in the Bill of Materials by 30%, decreasing the fail rate, and shortening the design cycle.
“Our partnership with Ambiq has helped to enable the BCL603S3L with an incredibly low power and high performing SIP. The support of the Apollo3 Blue provides smart ring manufacturers with improved flexibility, reliability, and power efficiency designed to minimize the development lifecycle,” said Zongming Jin, the CEO of Bravechip.
“Working with Bravechip helps bring our low-power solution to a specialized segment within digital health devices. Our Apollo3 Blue System-on-a-Chip within Bravechip’s Systems-in-a-Package will help to create even higher performing smart rings capable of meeting consumer needs,” said Terry Pan, VP of Sales, Ambiq China.
Ambiq says it has shipped more than 230 million units.
