Low power microcontrollers target medical
Ambiq is launching two ultra-low power microcontrollers aimed at medical designs and other devices in the Internet of Things (IoT)
The Apollo4 Lite microcontroller is based around a low power ARM Cortex-M4 core that can operate at up to 192 MHz, an audio subsystem, 2Mbytes of MRAM and 1.4Mbytes of low power SRAM. The device consumes 4µA/MHz when executing code from the MRAM and the 146 pin BGA package has a footprint of 5 x 5mm.
- Low power TinyML AI model for heart monitoring
- Ambiq cuts power in half with Apollo4 SoC
- Ambiq shows interest in FinFET, FDSOI
The Apollo4 Blue Lite adds Bluetooth Low Energy 5.1 running on an ARM Coretex-M0 core for IoT endpoint devices, especially the remote monitoring products of the healthcare sector. The package is actually smaller, using a system in package (SIP) design with 131 pins for a footprint of 4.7 x 4.6mm
Both use the proprietary Subthreshold Power-Optimized Technology (SPOT) platform, enabling new features while reducing devices’ overall system power consumption to extend the battery life.
This follows Ambiq’s announcement of an optimized open-source AI model utilizing multi-head neural networks (MH-NNs) to enable a variety of real-time heart-monitoring applications. The devices are also aimed at industrial monitoring and preventive maintenance using the machine learning algorithms, as well as smart home applications.
The Apollo4 Lite is pin compatible with Apollo4 Plus (AMAP42KP-KBR) while the Apollo4 Blue Lite is pin compatible with Apollo4 Blue Plus (AMA4B2KP-KXR).
“Today’s patients are more empowered to monitor and advocate for their own health, and healthcare providers require more data analytics to prescribe holistic treatment,” said David Priscak, VP of Technical Solutions at Ambiq. “With bold graphics and long battery life, state-of-the-art health tracking is now more affordable and accessible thanks to these new additions to our Apollo4 SoC family.”
