Intel ISP Adaptor-A2 for SF100 – ISP-ADP-INTEL-A2
Connect the SF100 to Intel motherboards
The ISP-ADP-INTEL-A2 connects a DediProg SF100 to the 2×10 SPI flash programming header on Intel motherboards, so you can program or emulate the board’s SPI flash in-system.
It mates with Intel’s 2×10 connector (Samtec ASP-159358-03) and comes on a cable about 8 cm long. The cable plugs into the adaptor through a connector, so you can detach it from the adaptor. Apart from the cable, it works the same as the ISP-ADP-INTEL-A.
Highlights
- Connects the SF100 to Intel motherboards
- Mates with the Intel 2×10 header (Samtec ASP-159358-03)
- Cable about 8 cm long; detachable from the adaptor
- Pull-up resistors on WP and HOLD

Signal Names: SF100 ISP header (2×7) to Adaptor
A few signals carry different names on the programmer header and on the Intel adaptor. They map as follows.
| Programmer pin | Signal | Adaptor pin | Signal |
|---|---|---|---|
| 3 | I/O2 or CS2 | 4 | CS1 |
| 5 | VCC | 6 | VCC |
| 7 | CS | 2 | CS0 |
| 12 | I/O3 | 3 | RESET |
Which Intel ISP Adaptor Do I Need?
A, B and C models have the cable soldered to the adaptor; A2, B2 and C2 models have a detachable cable. Otherwise each pair is the same.
| Model | Use with | Design notes |
|---|---|---|
| ISP-ADP-INTEL-A / ISP-ADP-INTEL-A2 | SF100 | Pull-up resistors on WP and HOLD. Model A also has jumpers tying WP/HOLD to VCC, which can stop some mainboards from booting |
| ISP-ADP-INTEL-B / ISP-ADP-INTEL-B2 | SF600, SF600Plus, SF600Plus-G2 | Pull-up resistors on WP and HOLD. No Quad I/O |
| ISP-ADP-INTEL-C / ISP-ADP-INTEL-C2 | EM100Pro, EM100Pro-G2, EM100Pro-G3, SF600, SF600Plus, SF600Plus-G2 | No resistors or jumpers on any pin. Quad I/O supported. For single I/O programming, the target board needs pull-ups on WP/HOLD |
Key Specifications
