Key Features
Overview
Professional SPI Flash Programming Solution
The Dediprog ISP-ADP-127 Cable Adaptor serves as an essential bridge between the industry-standard SF100 programmer pinout (2.54mm 2x7) and compact 1.27mm pin headers (SO8) commonly found on modern embedded applications. This precision-engineered adapter enables reliable in-system programming of SPI flash memory devices in space-constrained designs where traditional programming headers are impractical.
Seamless Integration with SF100 Family
Specifically designed for compatibility with Dediprog's proven SF100 SPI NOR Flash Programmer platform, this adapter maintains full signal integrity whilst adapting between pitch formats. The ISP-ADP-127 forms part of Dediprog's comprehensive ISP adapter range, which includes variants for different pitch requirements and programming scenarios.
Compact Design for Modern Applications
With the increasing miniaturisation of electronic devices, the 1.27mm pitch format has become increasingly prevalent in compact embedded designs. This adapter ensures engineers can programme SPI flash devices directly on-board without requiring specialised programming headers, reducing both PCB footprint requirements and manufacturing costs.
For engineers working with other pitch formats, consider the ISP-UADP-127 Universal Adapter for broader compatibility options, or explore our complete range of flash programming solutions.

Questions and Answers
-
What Signal Quality Considerations Apply When Using the ISP-ADP-127?
Keep the ISP cable short: Dediprog's application note gives 8 cm as the maximum. Dediprog also recommends series resistors on the SPI lines and a pull-up on CS where the host shares the bus.
-
Is the ISP-ADP-127 Suitable for Automated Production Programming?
The SF100 itself supports in-circuit test (ICT) set-ups and multi-programmer production use. Dediprog publishes no cycle-life data for the adapter.
-
What Are the Power Supply Requirements When Using the ISP-ADP-127?
The SF100 can power the target flash (3.3 V by default; 2.5 V or 1.8 V on hardware v3 and later; 50 mA maximum), or the target can be powered by the application board. Check the board's load fits within that limit if the SF100 supplies it.
-
How Does the 1.27mm Pitch Benefit Modern Embedded Designs?
A 1.27 mm pitch header fits space-constrained boards where a 2.54 mm header won't; Dediprog shows it fitted on an SO8 footprint.
-
What Debugging Capabilities Are Available When Using the ISP-ADP-127 with SF100?
The adapter is used with the SF100's software, which includes verify and blank check. The SF100 is a flash programmer, not a debugger; real-time debugging needs other tools.
-
What Pin Spacing Does the ISP-ADP-127 Adapter Convert Between?
It converts the SF100's 2.54 mm (0.1") 2x7 header to a 1.27 mm (0.05") 2x4 header, typically fitted on an SO8 footprint on the application board.
-
Which Dediprog Programmers Are Compatible with the ISP-ADP-127 Adapter?
The ISP-ADP-127 is designed for the Dediprog SF100 SPI NOR Flash Programmer. For SF600 series programmers, Dediprog provides separate universal adapters for their different pinout.
-
Can the ISP-ADP-127 Be Used for Programming Other Memory Types Besides SPI Flash?
It is designed for SPI flash programming with the SF100 and uses the SPI pinout of the SF100 header. The SF100 also programs some Freescale MCUs through EzPort.
-
What Is the Difference Between ISP-ADP-127 and ISP-UADP-127 Adapters?
The ISP-ADP-127 connects the SF100 directly to 1.27 mm headers. The ISP-UADP-127 Universal Adapter supports both 1.27 mm (2x4) and 2.54 mm (2x5) target headers, so it suits boards with a mix of header types.
-
How Does the ISP-ADP-127 Compare to More Expensive Programming Solutions Like SEGGER J-Link?
The ISP-ADP-127 is a purpose-built accessory for SPI flash programming with the SF100. SEGGER's Flasher PRO is a different kind of tool, a general production programmer; contact us if you are choosing between them.
