## Blueprint

**Closed design.** Saleae publishes only an electrical/specifications datasheet for the Logic 8; no schematic, PCB, or internal parts list is released.

### Design files

- datasheet: [Logic 8 data sheet (PDF)](https://downloads.saleae.com/specs/logic_8_data_sheet.pdf) (PDF)

_Notes:_ Checked saleae.com/logic and downloads.saleae.com; no schematic or BOM. Third-party teardowns exist for the related Logic Pro 8/16 (Cypress FX3 + FPGA) and the original 2010-era Logic (Cypress FX2LP), but I could not confirm which USB/controller chip the current (2016+) non-Pro Logic 8 actually uses, so no part is listed rather than guess.

## Specifications

### Capture limits

| | |
|---|---|
| Channels | Eight inputs; each records digital and analog. |
| Digital rates | 100 MS/s: ≤3 channels; 50: ≤6; 40: ≤7; 25: all eight. |
| Digital bandwidth | 25 MHz maximum. |
| Analog rates | 10 MS/s on two channels; 2.5 MS/s on eight. |
| Analog detail | 10-bit ADC; 1 MHz bandwidth at 10 MS/s. |
| Analog range | 0–5 V; readings saturate outside it. |
| Input impedance | 1 MΩ parallel with 10 pF. |
| Mixed capture | Available rates depend on enabled digital/analog channels and USB bandwidth. |

### Electrical and connection requirements

| | |
|---|---|
| Logic threshold | Support docs specify fixed VIL 0.6 V / VIH 1.2 V; see the documentation conflict below. |
| Intermediate voltages | Digital readings between 0.6 and 1.2 V are undefined. |
| Input protection | ±25 V protection is distinct from the 0–5 V analog measuring range. |
| Ground | Inputs, enclosure, USB and host share ground; the inputs are single-ended. |
| Probe ports | Two 2×4 headers; signal pins pair with common-ground pins. |
| USB | High-speed USB 2.0; Logic Pro USB 3 requirements are separate. |
| Temperature | 0–70 °C. |

### Software, package and revision

| | |
|---|---|
| Supported OS | Windows 10/11 x64; macOS 12+ Intel/Apple silicon; Ubuntu 20.04+ 64-bit and related systems. |
| Install | Windows installer includes the hardware driver; macOS app and Linux AppImage have separate instructions. |
| Capture duration | Host memory, signal activity and settings limit recording length. |
| Analysis and export | Protocol decoders, triggers, measurements; CSV, binary, VCD and MATLAB export. |
| Automation | Automation API and custom decoder support; use Logic 2 documentation. |
| Included kit | Two 4-channel harnesses, 16 clips, case, USB cable and starter guide. |
| Model boundary | Logic 8 is distinct from first-generation Logic, Logic Pro 8 and Logic Pro 16. |
