1. Introduction

The 32-bit USB Debug Adapter (UDA) provides the interface between the PC's USB port and the Silicon Labs 32-
bit target device's in-system debug/programming circuitry. The attached 10-pin debug ribbon cable connects the
adapter to the target board and the target device's 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.
