32-Bit SiM3xxxx USB Debug Adapter 32-BIT SiM3XXXX USB DEBUG ADAPTER USERS GUIDE 1. Introduction The 32-bit USB Debug Adapter (UDA) provides the interface between the PCs USB port and the Silicon Labs 32- bit target devices in-system debug/programming circuitry. The attached 10-pin debug ribbon cable connects the adapter to the target board and the target devices debug interface. Note: This USB debug adapter supports only SiM3xxxx variants of the Silicon Labs 32-bit MCU portfolio and none of the other devices that can be referred to as Silicon Labs 32-bit MCUs, including EFM32, EZR32, and EFR32 devices.

Pinout Specification The 32-Bit USB Debug Adapter supports both JTAG and Serial Wire debug interfaces, and the adapter is powered from the USB connection to the PC. The adapter uses the standard ARM CoreSight 10-pin connector. Table 1 shows the pin definitions for the UDA keyed connector. The part number for the matching shrouded and keyed con- nector for a PCB is FTSH-105-01-F-F-K from Samtec. More information on the CoreSight connectors can be found here:
