Semiconductor solutions developer Ambiq has partnered with Bravechip, a specialist in Artificial Intelligence of Things (AIoT) Systems in a Package (SIP) solutions and printed circuit board assembly (PCBA). Together, they have developed the BCL603S3L chiplet, which utilises the Apollo3 Blue System-on-a-Chip (SoC) to enhance energy efficiency, functionality, performance, and reliability in smart ring designs.
The BCL603S3L is a high-performance, ultra-low-power chiplet featuring the Apollo3 Blue as its master control, optimising the CPU to achieve power levels of 6 uA/MHZ. This significantly reduces active power consumption for various tasks, including heart rate monitoring, blood oxygen measurement, blood pressure tracking, sleep analysis, step counting, and 3DoF and 6DoF applications.
The Apollo3 Blue SoC includes BLE 5.2, embedded low-power Bluetooth protocol stacks, and GATT services, enabling smart rings to connect seamlessly with smartphones. Its integration allows for a more compact design with a 4*6.8mm LGA package, enabling smart ring manufacturers to use a two-layer FPC board, which reduces the number of BOMs by 30%, decreases the fail rate, and shortens 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,” explained Zongming Jin, CEO of Bravechip.
“Working with Bravechip helps bring our low-power solution to a specialised 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,” added Terry Pan, VP of Sales, Ambiq China.
