Product details
Overview
SLWSTK6201A from Silicon Labs is a wireless MCU evaluation kit based on the EZR32LG330F256R68G SoC, integrating an ARM Cortex-M3 core, 256 kB flash, 32 kB RAM, sub-GHz EZRadioPRO transceiver (142–1050 MHz), USB interface, and ultra-low-power LESENSE/LEUART peripherals. It enables rapid prototyping of battery-powered smart metering, home automation, and sensor network applications.
For engineers reviewing the SLWSTK6201A datasheet, SLWSTK6201A pinout, SLWSTK6201A application, or SLWSTK6201A equivalent, this page delivers verified hardware configuration, RF performance metrics, energy mode behavior, peripheral routing details, and real-world use-case implementation guidance - all specific to the SLWSTK6201A evaluation platform and its onboard EZR32LG330F256R68G MCU.
Technical Context
The SLWSTK6201A implements the full EZR32LG330F256R68G reference design, featuring a 48 MHz ARM Cortex-M3 CPU with hardware AES-128/256 acceleration, 12-bit 1 Msps ADC, dual 12-bit DACs, two operational amplifiers, and LESENSE supporting up to 16 sensors in EM2. Its RF subsystem uses the EZRadioPRO transceiver with –133 dBm sensitivity and +20 dBm output power, compliant with IEEE 802.15.4g and WM-Bus standards.
Communication between MCU and radio occurs via dedicated USART0 (PE10–PE12), GPIO-controlled nIRQ (PE13), SDN (PE8), and nSEL (PE9), with PRS-routed GPIO0/GPIO1 (PA15/PE14) enabling antenna diversity and TRSW control. All timing-critical RF functions operate under CMU-managed clock domains including HFXO, HFRCO, and LFRCO.

FAQ
What is the primary function of the SLWSTK6201A evaluation kit?
The SLWSTK6201A is a fully assembled and debug-ready evaluation platform for the EZR32LG330F256R68G wireless MCU. It provides immediate access to all MCU peripherals-including USB, sub-GHz RF, LESENSE, and dual LEUART-enabling rapid development of certified 802.15.4g and WM-Bus applications. The SLWSTK6201A includes onboard J-Link debugger, SMA antenna connector, and expansion headers compatible with Silicon Labs' Simplicity Studio toolchain.
Does the SLWSTK6201A support both EZRadio and EZRadioPRO transceivers?
No - the SLWSTK6201A is configured exclusively with the EZRadioPRO transceiver variant (EZR32LG330F256R68G), delivering –133 dBm receive sensitivity and +20 dBm output power across 142–1050 MHz. It does not support EZRadio-only variants like R55G. The board's RF layout, matching network, and calibration data are optimized for EZRadioPRO performance and regulatory compliance (FCC/ETSI/ARIB).
Can the SLWSTK6201A be used for production deployment?
The SLWSTK6201A is intended for evaluation and development only. While it contains the same EZR32LG330F256R68G MCU used in production designs, its PCB layout, antenna structure, and power regulation are not qualified for volume manufacturing or certification. For production, designers must implement the SLWSTK6201A's reference schematics and layout guidelines into their own board, using the official EZR32LG330F256R68G QFN64 package and validated RF matching components.
What debug interfaces are available on the SLWSTK6201A?
The SLWSTK6201A integrates a Segger J-Link OB debugger supporting SWD (2-pin serial wire debug), ETM trace, and 1-wire SWV for real-time profiling. It exposes DBG_SWCLK, DBG_SWDIO, and DBG_SWO pins via the 10-pin debug header, and supports full-speed USB CDC virtual COM port for LEUART/UART logging. The SLWSTK6201A also enables seamless flashing and debugging directly through Simplicity Studio without external tools.
How is RF communication routed between the MCU and transceiver on the SLWSTK6201A?
On the SLWSTK6201A, the EZR32LG330F256R68G communicates with its onboard EZRadioPRO transceiver via dedicated signals: USART0 (PE10–PE12) for SPI-like data transfer, PE8 (SDN) for shutdown control, PE9 (nSEL) for chip select, PE13 (nIRQ) for interrupt signaling, and PA15/PE14 (GPIO0/GPIO1) routed via PRS for TRSW and antenna diversity control. This routing matches Table 3.1 in the EZR32LG330 datasheet and is fixed on the SLWSTK6201A PCB.
