Product details
Overview
SLWSTK6020B from Silicon Labs is a Bluetooth Low Energy development kit based on the EFR32BG22 SoC, integrating a 32-bit ARM Cortex-M33 core, dual-band (2.4 GHz / Sub-GHz) radio, hardware cryptographic accelerators, and ultra-low-power peripherals. It supports BLE 5.2, proprietary protocols, and IoT sensor node development with integrated balun and DC-DC converter.
For engineers reviewing the SLWSTK6020B datasheet, SLWSTK6020B pinout, SLWSTK6020B application, or SLWSTK6020B equivalent, this kit enables rapid prototyping of battery-powered wireless edge nodes requiring secure, low-latency, multi-protocol connectivity - especially where RF performance validation, power profiling, and protocol stack integration are critical.
Technical Context
The SLWSTK6020B hosts the EFR32BG22B222F512IM40-C chip: a single-die SoC combining a 78 MHz ARM Cortex-M33 with TrustZone, 512 kB flash/32 kB RAM, and a fully integrated 2.4 GHz + Sub-GHz transceiver supporting BLE 5.2, IEEE 802.15.4, and proprietary PHYs. Its radio architecture uses fractional-N synthesizer, low-IF receiver, and direct-conversion transmitter with configurable shaping filters and hardware-accelerated modulation.
Power management includes an on-board buck DC-DC converter (supporting up to 200 mA), programmable voltage monitor, and seven energy modes (EM0–EM4). Clocking relies on internal HF/LF RC oscillators plus external 39 MHz and 32.768 kHz crystals for precision timing across all operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | ARM Cortex-M33 @ 78 MHz with TrustZone security and DSP extensions - enables secure firmware execution and real-time signal processing in resource-constrained edge devices. |
| Memory | 512 kB flash / 32 kB RAM - sufficient for BLE stack + application logic + OTA updates without external memory. |
| Radio Bands | 2.4 GHz (BLE/proprietary) and Sub-GHz (868/915 MHz) - supports global regulatory compliance and long-range, low-interference operation. |
| TX Power | +6 dBm @ 2.4 GHz, +10 dBm @ Sub-GHz - delivers robust link budget for indoor and outdoor sensor deployments. |
| Current Draw | 1.2 µA in EM4 (Shutoff), 1.8 µA in EM2 (Deep Sleep w/ RTC) - extends coin-cell battery life to multi-year operation. |
| Crypto Acceleration | Hardware AES-128/256, SHA-256, ECC, TRNG - offloads encryption from CPU, reducing latency and power during secure boot and TLS handshake. |
| Peripherals | 12-bit SAR ADC, 2x Op-Amps, 2x Comparators, LESENSE, PRS, 2x UARTs (including LEUART), I²C, SPI - enables direct analog sensor interfacing and autonomous peripheral coordination without MCU wake-up. |

FAQ
What is the primary function of the SLWSTK6020B development kit?
The SLWSTK6020B is a complete evaluation and development platform for the EFR32BG22 Bluetooth Low Energy SoC. It provides debug interfaces (JTAG/SWD), onboard current measurement, RF matching networks, antenna options (PCB + u.FL), and expansion headers - enabling full hardware validation, power profiling, and firmware development for battery-powered IoT edge devices before custom PCB spin.
Does the SLWSTK6020B support both 2.4 GHz and Sub-GHz wireless operation out of the box?
Yes. The SLWSTK6020B is pre-configured to evaluate both frequency bands using the same EFR32BG22 SoC. It includes matched RF paths for 2.4 GHz (with integrated balun) and Sub-GHz (868/915 MHz), selectable via hardware jumpers and software configuration - allowing simultaneous protocol testing and regulatory pre-scan without hardware modification.
Can the SLWSTK6020B be used for production programming of EFR32BG22-based boards?
Yes. The SLWSTK6020B integrates a Segger J-Link debugger and supports mass production programming via Simplicity Studio's Flash Programmer tool. It can program external target boards through its 10-pin SWD header and also serve as a standalone programmer/debugger for other EFR32 devices - eliminating need for separate programming hardware in early manufacturing stages.
What power measurement capabilities does the SLWSTK6020B provide for low-energy optimization?
The SLWSTK6020B features real-time, high-resolution current measurement (down to 100 nA resolution) across all energy modes (EM0–EM4), accessible via Simplicity Studio's Energy Profiler. It measures SoC current draw independently from debugger and USB power, enabling precise correlation between firmware events (e.g., radio transmit, ADC sampling) and microamp-level power consumption - critical for optimizing battery lifetime.
Is the SLWSTK6020B compatible with Silicon Labs' Bluetooth SDK and Simplicity Studio IDE?
Yes. The SLWSTK6020B is fully supported by Silicon Labs' official Bluetooth SDK v3.x+ and Simplicity Studio v5. This includes pre-certified BLE stack examples (GATT server/client, OTA DFU), hardware abstraction layer (HAL) drivers, and graphical configuration tools for radio settings, peripherals, and energy modes - ensuring seamless integration into standard Silicon Labs development workflows.
