Meet the Biomedical-Lab-On-Chip from Onera; An Ultra-Low-Power Biomedical Sensor Hub

MedTech Company, Onera Technologies in league with IMEC recently announced the launch of its latest product; the Onera Biomedical-Lab-On-Chip – an ultra-low-power biomedical sensor hub, designed to accelerate the development of wearable health devices.

Announced barely two days to the just concluded CES 2022, the biomedical system-on-chip is the first in the class by Onera, following its celebrated sleep diagnostic solutions, and it embeds clinical-grade physiological measurements and analysis systems to revolutionize the development of high-grade miniaturized wearable devices.

Based on Arm Cortex – M4f CPU, the Onera Biomedical-Lab-On-Chip is equipped with a multi-channel sensor readout system along with built-in power management, data processing, and interfacing features. It supports on-chip biomedical sensing and data retrieval with ten readouts for ExG, including EEG, ECG, EMG, EOG, and two readouts for photoplethysmography along with two bioimpedance readouts. The chip also embeds a 320kB SRAM and 768kB flash, along with embedded digital filters and an accelerator block which features a data compactor, sampling block, processor, FIFO, and DMA and synchronization engines all of which facilitate on-chip data processing and support for a broad range of wearable health applications and devices.

Designed for use in wearable devices and applications across the medical health and wellness industry, the Biomedical-Lab-on-Chip features digital interfaces like SPI, I2C, I2S, UART, and GPIOs which aids its integration with other subsystems.

Key features and specifications of the biomedical sensor hub SoC include:

• CPU:
  • Arm Cortex – M4f with DSP, FPU, 3x AHB – Lite, JTAG, supporting ITM trace, Data watchpoint, Nested Vectored Interrupt
• Power Input: 0.8V – 3.6V (single supply)
• Memory: 320 kB SRAM
• Storage: 768 kB flash
• Analog Readouts: 
  • 10x ExG including EMG, ECG, EOG, and EEG; 2x PPG – photoplethysmography, 4x LED drivers, 2x Bioz MF, 2x Bioz CG
• Digital Interfaces:
  • 4x SPI, 4x I2C, 2x I2S, 2x UART, 48x GPIO
• Accelerators:
  • Matrix processor, Sample rate, Data compactor, DAT synchronization, FIFO, DMA
• Misc:
  • System timing, Power management: 2x HP LDO @ 50mA, 2x LDO and Buck -boosters (7x outputs)

Onera plans to make the Biomedical-Lab-on-Chip available for commercial use to all and sundry and while there is no clear distribution/price information yet, it is said to be in the works and should hit the shelves soon.
