Isolation Board for SF600/SF600 Plus
The SF600-ISO-Board-2 is designed to minimise cable-based interference and protect against ground loop damage when Dediprog SF600 and SF600 Plus programmers are directly attached to a target motherboard for SPI Flash in-system programming. This robust isolator sits between the programmer and the device cable, maintaining reliable motherboard boot operation and preventing costly damage to both programmer and target board in high-noise engineering test setups.
Ground Loop Protection
Ground loops occur when multiple ground paths exist between programmer and target, creating circulating currents that can damage sensitive components. The SF600-ISO-Board-2 breaks these hazardous current paths whilst maintaining signal integrity, safeguarding expensive equipment in industrial and lab environments where multiple power supplies and test instruments share common grounds.
Pinout and Wiring Quick-Start
| Signal Name | Pin | Connection |
|---|---|---|
| VCC | 1 | Target Board Power |
| SPI_CS | 2 | Chip Select |
| SPI_CLK | 3 | SPI Clock |
| SPI_MOSI | 4 | Data In |

| GND | 6 | Ground (Isolated) |
Application Example
Fit SF600-ISO-Board-2 between the programmer and your target for improved stability when flashing SPI memories, reducing risk of failed boots caused by signal reflections or ground loops common in long cable runs and multi-instrument test benches.
