A 16-channel programmable electrical stimulation ASIC for implantable and external neuromodulation systems. It generates stimulus waveforms autonomously — the host MCU configures parameters over SPI, then sleeps. Channels are configurable as monopolar, bipolar, or multipolar, and expand to 32 or 64 channels via daisy-chain.
DBS, SCS, cochlear, peripheral nerve stimulation
Brain-computer interface stimulation front ends
NMES, rehabilitation, research systems
Any system requiring programmable multi-channel current output
85 µA average draw in DBS mode (2 ch, 3 mA, 130 Hz, 90 µs, 1 kΩ), total system power under 2 mW. For implantables, this is battery life. For externals, it's thermal budget.
Both modes, hardware-native, single register select — no additional circuitry required.
Autonomous: MCU configures via SPI, then sleeps. MCU-driven: step-by-step control for asymmetric, multi-phase, custom-shaped pulses.
Real-time resistive + capacitive measurement (50 Ω–10 kΩ), even during active stimulation, for electrode-tissue interface monitoring.
Hardware fault detection with dedicated status signaling. The chip surfaces the error; firmware decides the response.
Complex stimulation protocols — burst trains, ramp-up/ramp-down — configured via registers and executed internally, with no MCU overhead.

The CASE electrode functions as an independent 17th channel in silicon. Connect additional chips on the same SPI bus to daisy-chain to 32 or 64 channels.
No sales calls, NDAs, or purchase commitments to get started. The datasheet, protocol spec, firmware library, and an evaluation board are available right away, so you can prototype, characterize, and decide whether OpenStim Core fits your design on your own timeline. When you're ready to move into characterization builds or production, a straightforward volume agreement opens up the rest — full register access, validation support, and supply commitments.
Anyone — research labs, academic researchers, startups, engineers prototyping or exploring a design. No contract or declaration of intent required, including for research labs running studies or characterization work.
Characterization builds, V&V, IQ/OQ/PQ runs, or production. Requires a signed Volume Agreement with Device Commons.
USB Type-C at 5 V powers the board automatically, or run from a Li-cell or bench supply for higher compliance voltage.
Connect UART via the BR9 header and send configuration commands. All stimulus parameters are register-mapped over SPI at 100 kHz.
Measure at the EP1–EP16 test points, with on-board 1 kΩ load resistors available per channel, or connect your own load.
Tier 1 documentation and the DC-6002 evaluation board are available to qualified teams — no contract required. Contact us to request access; we typically respond within one business day.
