What happened
Sipeed has launched the SLogic32U3, a USB-C logic analyzer that the company positions as the first 10 Gbps USB 3.2 logic analyzer on the market.S1 The device is the successor to the SLogic16U3 3.2 Gbps logic analyzer that Sipeed released in 2025.S1
The SLogic32U3 exposes 32 digital input channels routed through four mini HDMI connectors (eight channels each), with 350 MHz signal bandwidth and a 0–10 V signal input range with adjustable threshold.S1 The source did not disclose the FPGA vendor, noting only that it is "not mentioned (potentially from GOWIN)."S1
Per-channel sample rate scales with active channel count: 1400 MS/s with four channels, 800 MS/s with eight channels, 400 MS/s with sixteen channels, and 200 MS/s when all thirty-two channels are in use.S1 Capture is performed in a stream mode with real-time readback backed by a 2 Gbit DDR3 FIFO buffer, with usable depth limited by PC memory and disk.S1 Sipeed also offers an ADC module as an optional add-on, expanding the platform into mixed-signal capture.S1

Background timeline
- - Sipeed released the SLogic16U3, a 3.2 Gbps logic analyzer positioned as the predecessor to the SLogic32U3. [S1]
- - Sipeed launched the SLogic32U3 crowdfunding campaign for a 10 Gbps USB 3.2, 32-channel logic analyzer with optional ADC module. [S1]
XAIPART take
Technical impact
The headline shift from 3.2 Gbps on the SLogic16U3 to 10 Gbps on the SLogic32U3 lifts the USB bottleneck and lets the analyzer stream continuously rather than rely on deep onboard RAM.S1 The 2 Gbit DDR3 FIFO plus PC-side buffering means capture depth is effectively tied to host storage, which suits long-duration protocol or power sequencing traces where the prior generation had to gate sample rate to fit local memory.
The tiered sample-rate curve (1400 MS/s at 4 channels down to 200 MS/s at 32) is consistent with a shared high-speed SERDES inside the FPGA, so buyers planning 32-channel use should expect edge timing, not full Nyquist, on every line simultaneously.
Market impact
10 Gbps streaming changes the cost calculus for bench equipment. Engineers who previously rented time on mid-range USB logic analyzers from established test-instrument vendors may now consider a crowdfunding-tier device when long captures are the bottleneck.
Supply is the open question: the unit is in crowdfunding as of 2026-10-09, and the source did not disclose shipment dates, retail pricing, or distributor channels, so procurement teams should treat allocation as single-source and unconfirmed until retail listings appear.
Action
For design and validation teams evaluating the SLogic32U3, shortlist it where 32 channels plus sustained streaming are required and the 350 MHz bandwidth ceiling matches the signaling under test.
Buyers should confirm FPGA vendor, ADC module pricing, and bundled probe harness directly, since the source did not disclose these. Hold a fallback slot on an established USB logic analyzer line in parallel until the crowdfunding ships and independent benchmarks are published.
XAIPART Forecast
If the SLogic32U3 ships to backers by Q2 2027 with a publicly listed retail channel and at least one independent review confirms sustained 1400 MS/s capture on all four active channels, XAIPART expects competing 32-channel USB logic analyzer SKUs from at least one established test-instrument vendor to add a USB 3.2 streaming mode within 9 months of that confirmation; otherwise this forecast is wrong.
