Austin, TX – Ambiq®, a pioneer of ultra-low-power semiconductor solutions based on the proprietary and patented Subthreshold Power Optimized Technology (SPOT®) platform, today announced the general availability of Apollo4 Blue Plus supporting Bluetooth Low Energy connectivity, enhanced graphics display, and audio capabilities, and flexible security features to safely deploy power-constrained IoT endpoint devices without compromising power efficiency.
According to Ericsson® Mobility Visualizer, the installed base of connected IoT devices is expected to grow from 14.6 billion devices in 2021 to 30.2 billion devices in 2027. The wearables market in particular, including smartwatches, smartbands, and smart glasses, together will generate more than $350 billion in cumulative revenues over the next five years¹. To address the IoT market, some of the key design challenges to overcome include power consumption, on-chip intelligence, complex integration, and interaction with the outside world.
The Apollo4 Blue Plus is the 4th generation system processor product built upon Ambiq’s proprietary SPOT platform. The Apollo4 Blue Plus has an integrated CPU and sophisticated graphics rendering capability, allowing developers to compose high-resolution UI with vibrant images, and enabling additional features while reducing devices’ overall system power consumption to extend their battery life. Its embedded 4.75MB of memory delivers power-efficient display performance by storing images on-chip to avoid resources by fetching data from external memory. Additionally, the ample memory size enables an end-to-end always-on-voice capability to support high quality voice calls and music playback in concert with the high-fidelity Pulse Density Modulation (PDM) to Pulse Code Modulation (PCM) converter which supports up to four stereo pairs of digital microphones with a dynamic range of up to 120 dB. The Apollo4 Blue Plus also has flexible audio interfaces with full duplex I2S and asynchronous sample rate conversion (ASRC), which will be helpful when driving a speaker.
“IoT endpoint original equipment manufacturers increasingly demand the most high-performing, power-efficient, integrated, and compact semiconductor,” said Dan Cermak, VP of Architecture and Product Planning at Ambiq. ” Our ultra-low-power semiconductor solutions fundamentally address our end customers’ needs for low-power processing, connectivity, and AI.”
The latest addition to the Apollo4 family provides enhanced graphics display and greater voice capabilities to serve as either an application processor or a coprocessor for battery-powered endpoint devices. The Apollo4 Blue Plus is now in mass production, targeting smartwatches and smart bands, consumer medical devices, motion and tracking units, and the smart home of the 21st century.
