Professional ARM Cortex Programming Cable
The CORTEXRIBBON10-L is a specialised reversed 10-pin ribbon cable engineered for ARM Cortex debugging and programming applications. This cable features the LEMTA (reversed) configuration specifically designed for use with Atmel ICE debuggers, which require pin-reversed connectivity to maintain correct signal mapping.
Wiring Quick-Start
| Pin | Signal | Description |
|---|---|---|
| 1 | VTRef | Target reference voltage |
| 2 | SWDIO/TMS | Serial Wire Data I/O / Test Mode Select |
| 3 | GND | Ground |
| 4 | SWCLK/TCK | Serial Wire Clock / Test Clock |
| 5 | GND | Ground |
| 6 | SWO/TDO | Serial Wire Output / Test Data Out |
| 7 | KEY | Not connected (keying pin) |
| 8 | NC/TDI | Not connected / Test Data In |
| 9 | GND | Ground |
| 10 | nRESET | Reset signal (active low) |
Connection Instructions
Connect the female IDC connector to your ARM Cortex programmer/debugger 10-pin male header. The reversed LEMTA orientation corrects for Atmel ICE's non-standard pin numbering where pin 1 is physically located at pin 10 position.
Important: The LEMTA version is essential for Atmel ICE compatibility. Standard orientation cables will cause signal conflicts and potential hardware damage.
Compatible Interfaces
- Serial Wire Debug (SWD) - 2-wire debugging protocol
- JTAG - 4-wire IEEE 1149.1 standard interface
- Serial Wire Output (SWO) trace support
This cable bridges the gap between your Atmel ICE debugger and target boards featuring the standard 10-pin 50mil (1.27mm) FTSH-style headers, enabling seamless programming and debugging workflows.
