This cable connects ARM Cortex programmers and debuggers (such as ULINK and Black Sphere) to a target with a 10-pin 50mil FTSH style header. (The standard 10-pin Cortex header).

The connectors fitted to this cable are Harwin M50-3300542 or equivalent and mate with e.g. Samtec FTSH family headers.

Buying this? Why don’t you design in our tiny ZERO COST Tag-Connect footprints for Cortex instead? Our TC2030 -NL footprints occupy under 1/3 the board space of the Samtec FTSH 10-pin header and are infinitely cheaper! No Header! No Brainer!

WARNING for ATMEL-ICE users: The Atmel-ICE has it’s header pin numbers reversed (standard pin 1 is Atmel-ICE’s pin 10). To use our cable with Atmel’s reversed pin-number header you’ll either need to cut off one a locating lug from one ribbon connector and plug it in backwards, This cable is the LEMTA version with one of the 10-pin ribbon connectors fitted backwards. If you plug in a standard (correct) Cortex cable you’re going to short power and stuff out.

The Tag Connect Reversed 10-pin Cortex Ribbon Cable -LEMTA addresses the unique requirements of Atmel ICE users who need reliable connectivity to ARM Cortex-based targets. Unlike standard cables, this version features reversed pin mapping to compensate for Atmel ICE's non-standard connector orientation, preventing signal conflicts and ensuring proper debugging functionality.

The cable utilises 50mil (1.27mm) pitch connectors compatible with FTSH-105-01 style headers commonly found on ARM development boards. Its 4-inch length provides optimal signal integrity while maintaining workspace flexibility. Engineers working with ARM Cortex-M, Cortex-R, and Cortex-A processors will find this cable essential for professional debugging workflows.

Standard cables would create signal conflicts due to Atmel ICE's non-standard pin numbering where pin 1 is located at the pin 10 position. - 1570614: Which ARM processors are supported by this cable?***SIMP***This cable supports all ARM Cortex-M, Cortex-R, and Cortex-A processors that use the standard 10-pin debug interface, including STM32, SAM, Kinetis, and LPC series microcontrollers. - 1570615: Can I use this cable with debuggers other than Atmel ICE?***SIMP***While designed for Atmel ICE, this cable works with any debugger that requires the LEMTA reversed configuration. However, standard orientation debuggers like J-Link require regular orientation cables. - 1570616: What's the difference between SWD and JTAG on this cable?***SIMP***SWD uses 2 wires (SWDIO, SWCLK) for debugging and is more common on Cortex-M devices. JTAG uses 4 wires (TDI, TDO, TMS, TCK) and supports boundary scan testing. This cable supports both protocols. - 1570617: What does the 50mil pitch specification mean?***SIMP***50mil refers to the 1.27mm spacing between pins on the connector. This matches the FTSH-105-01 style headers commonly used on ARM development boards and ensures proper physical fit. - 1570618: Is the 4-inch cable length sufficient for most applications?***SIMP***Yes, the 4-inch length balances signal integrity with workspace flexibility. Longer cables can introduce signal degradation, especially for high-speed debugging protocols. - 1570619: Does this cable provide power to the target board?***SIMP***No, this is a signal cable only. Pin 1 (VTRef) is used as a voltage reference for the debugger's level shifters, not for powering the target. Your target board needs separate power. - 1570620: What happens if I use a standard cable with Atmel ICE?***SIMP***Using a standard cable would reverse all signals, potentially shorting power lines and causing permanent damage to both the debugger and target board. Always use LEMTA cables with Atmel ICE. - 1570621: Can this cable handle trace data output?***SIMP***Yes, pin 6 supports SWO (Serial Wire Output) for trace data when using SWD mode. This enables real-time trace capabilities for performance analysis and debugging. - 1570622: What's the maximum programming speed supported?***SIMP***The cable supports speeds up to 50MHz for JTAG/SWD protocols, matching the capabilities of modern ARM Cortex debuggers. Actual speed depends on your debugger and target board design.
