The VivoSoC 2.001 is an incremental tape-out of VivoSoC platform for biomedical signal acquisition. This chip is feature rich and designed to be potentially employed in different portable applications, e.g.: mass-market consumer fitness tracker, medical-grade teleheath point-of-care, implantable devices for chronic disease monitoring and management.
To fit the tight energy budgets of portable devices, the operating point of each SoC block can be fine tuned to trade-off unnecessary precision with power.
Main chip features:
- Quad-core RISC processor of the PULP family equipped with SPIs, UART, GPIOs, JTAG and I2C digital interfaces and a L2 memory of 128kB.
- PULP cluster and peripherals embedded in two independent voltage and clock domain regions to allow voltage and frequency scaling.
- 9-channels 12kHz-66dB analog-front-end for time-multiplexed ExG recording (with lead-off detection).
- 4-channels Transimpedance Medical Amplifier and LEDs driver for photoplethysmogram (PPG).
- 2-channels Bio-Impedance analog-front-end.
- 3 fully flexible SAR-ADC for digitizing biomedical signals (ExG, PPG, bio-impedance).
- 6-channels nerve blocking and stimulation circuit.
- General purpose algorithmic ADC for auxiliary sensor recordings.
- On-chip LDOs to provide a clean supply for the analog circuits.
- On-chip clock-generator and biasing.
The name VivoSoC is based on the Italian word "Vivo" that can be translated as "Alive".
