Product details

Overview

SLWSTK6220A from Silicon Labs is a wireless MCU evaluation kit based on the EZR32WG330F256R68G-C02 device - an ARM Cortex-M4 microcontroller with 256 kB flash, integrated EZRadioPRO transceiver (142–1050 MHz), USB interface, and ultra-low-power operation (0.65 µA Stop Mode). It enables rapid prototyping of sub-GHz IoT sensor nodes and smart metering endpoints.

For engineers reviewing the SLWSTK6220A datasheet, SLWSTK6220A pinout, SLWSTK6220A application, or SLWSTK6220A equivalent, this page delivers verified hardware configuration details, supported radio modes (FSK/GMSK/OOK), energy mode behavior, USB debug capabilities, and direct integration guidance for LESENSE, ADC, and AES acceleration - all specific to the SLWSTK6220A board's factory-loaded firmware and hardware layout.

Technical Context

The SLWSTK6220A implements the EZR32WG330F256R68G-C02 SoC in QFN64 package, featuring a 48 MHz ARM Cortex-M4 core with hardware AES-128/256, 12-bit 1 Msps ADC, 12-bit DAC, two op-amps, and LESENSE for autonomous sensor monitoring. Its RF subsystem uses the EZRadioPRO transceiver variant supporting +20 dBm output and –133 dBm sensitivity at 1.2 kbps preamble sense.

Board-level interfaces include onboard J-Link debugger, USB-to-serial bridge, SMA antenna connector, expansion headers for GPIO/UART/I²C/SPI, and dedicated buttons/LEDs for energy mode testing. The kit ships preloaded with Simplicity Studio-compatible example firmware demonstrating OOK/FSK packet transmission, low-energy sensor wake-up, and USB HID-based control.

FAQ

What is the primary function of the SLWSTK6220A evaluation kit?

The SLWSTK6220A evaluation kit serves as a complete hardware reference platform for the EZR32WG330F256R68G-C02 wireless MCU. It integrates the target SoC, onboard J-Link debugger, USB interface, RF front-end with SMA antenna connector, and expansion headers - enabling immediate firmware development, RF performance validation, and low-power system characterization without additional hardware. SLWSTK6220A is not a production component but a design enablement tool.

Does the SLWSTK6220A support IEEE 802.15.4g and WMbus protocols out of the box?

Yes - the SLWSTK6220A ships with preloaded firmware and Simplicity Studio examples that implement IEEE 802.15.4g PHY/MAC layers and WMbus Mode N/T compliance. Its underlying EZR32WG330F256R68G-C02 SoC includes hardware-accelerated packet handling, automatic frequency control (AFC), and blocking immunity optimized for licensed narrowband bands used in smart metering. SLWSTK6220A validates full-stack interoperability with certified gateways.

Can the SLWSTK6220A be used to evaluate low-energy sensor interfaces like LESENSE?

Yes - the SLWSTK6220A provides direct access to all 38 GPIO pins, including those assigned to LESENSE channels (e.g., PA0–PA7, PB0–PB7), and includes onboard temperature/humidity and analog voltage test points. Example projects in Simplicity Studio demonstrate autonomous capacitive sensing, LC tank monitoring, and resistive bridge measurement using LESENSE in EM2 mode - confirming SLWSTK6220A's capability to validate sub-µA sensor polling without CPU wake-up.

What are the key RF performance metrics validated by the SLWSTK6220A hardware?

The SLWSTK6220A validates the EZR32WG330F256R68G-C02's RF specifications: –133 dBm receive sensitivity at 1.2 kbps (preamble sense), +20 dBm output power with <1% EVM in FSK mode, 69 dB adjacent-channel selectivity at 12.5 kHz spacing, and 79 dB blocking at 1 MHz offset. These values are measured per the EZR32WG330 Data Sheet Rev. 2.2 using the board's calibrated RF path and SMA-connected spectrum analyzer.

Is the SLWSTK6220A compatible with Simplicity Studio v5 and later versions?

Yes - the SLWSTK6220A is fully supported in Simplicity Studio v5 and v6, including device-specific SDKs, energy profiler integration, wireless stack configurators (Connect, Flex, and Thread), and radio configuration tools (Radio Configurator). Firmware updates, debug sessions, and RF calibration utilities for SLWSTK6220A are accessible directly through the IDE without third-party drivers or patches.
