SEGGER STDC 14 Adapter - 20-pin to 14-pin Debug Connector

Product Code: 8.06.39

Technical Overview The SEGGER STDC 14 Adapter represents a critical interface solution for embedded systems developers working with STMicroelectronics' STDC14 connector standard. This passive adapter seamlessly bridges the gap between SEGGER's industry-standard 20-pin 0.1" J-Link connector and the compact 14-pin 0.05" STDC connector, maintaining full electrical compatibility across all supported debugging protocols. Connector Specifications STDC14 Pinout Compatibility: Pins 3-12 follow the standard ARM Cortex-M 10-pin debug connector specification, with pins 1-2 reserved and pins 13-14 providing UART functionality for Virtual COM port features.

Simply connect the adapter's 20-pin connector to your J-Link or Flasher probe, then connect the included 14-pin ribbon cable to your target system's STDC14 connector. STDC14 Connector Orientation: Pin 1 typically marked with square pad or dot notation on target boards Compatible Hardware The adapter supports the complete range of SEGGER debug probes including J-Link Pro PoE, J-Link Pro, J-Link ULTRA+, J-Link WiFi, J-Link PLUS series, and J-Link BASE series. All Flasher models are equally supported, providing maximum flexibility across development environments. Target Applications Primary applications include STM32 evaluation boards, custom STM32 designs, and any embedded system implementing the STDC14 connector standard. The adapter proves especially valuable in production environments where existing J-Link infrastructure must interface with newer STDC14-equipped targets.
