Product details

Overview

SLWSTK6020A from Silicon Labs is a Bluetooth Smart SoC evaluation kit based on the EFR32BG1P332F256GM48-B0 wireless MCU, featuring a 40 MHz ARM Cortex-M4 core, 256 kB flash/32 kB RAM, integrated 2.4 GHz radio with 19.5 dBm TX power, and hardware crypto acceleration for AES-256/SHA-256/ECC - deployed in smart lock, BLE sensor node, and home automation gateway reference designs.

For engineers reviewing the SLWSTK6020A datasheet, SLWSTK6020A pinout, SLWSTK6020A application, or SLWSTK6020A equivalent, this page delivers verified technical context, energy mode behavior (EM2: 1.4 μA), radio architecture (low-IF receiver, -94 dBm sensitivity @ 1 Mbit/s), peripheral reflex system autonomy, and certified Bluetooth stack compatibility - all critical for low-power IoT firmware development and RF validation.

Technical Context

The SLWSTK6020A hosts the EFR32BG1P332F256GM48-B0 SoC, which integrates a 40 MHz ARM Cortex-M4 with FPU/DSP extensions, 256 kB flash, and 32 kB RAM. Its radio subsystem uses a fractional-N synthesizer with <100 Hz frequency resolution, low-IF receiver architecture (150–1371 kHz IF), and direct-conversion transmitter supporting GFSK, 2/4-FSK, and shaped OQPSK.

Power management includes EM0–EM4 energy modes, DC-DC converter with RF noise mitigation (90% efficiency, 200 mA output), and autonomous wake-on-radio via RAC/PRS. Security relies on hardware CRYPTO engine supporting full AES-256, SHA-256, ECC (P-256/K-233), and true random number generation from RF entropy.

Key Specifications

Parameter	Value and Actual Design Meaning
Core	ARM Cortex-M4 @ 40 MHz with FPU/DSP - enables real-time signal processing for BLE audio or sensor fusion without external DSP.
Memory	256 kB flash / 32 kB RAM - sufficient for concurrent BLE stack (v4.2), custom application, and OTA update staging buffer.
Radio TX Power	19.5 dBm max - achieves >100 m line-of-sight range in 2.4 GHz ISM band with integrated PA and balun.
RX Sensitivity	-94 dBm @ 1 Mbit/s GFSK - ensures robust link budget in noisy environments like retail or industrial settings.
Lowest Active Current	63 μA/MHz in EM0 - minimizes battery drain during active BLE connection handling and sensor polling.
Deep Sleep Current	1.4 μA in EM2 (RAM retention + RTCC) - supports multi-year operation on coin-cell batteries in periodic beaconing applications.
Crypto Support	Full hardware acceleration: AES-128/256, SHA-1/224/256, ECC over GF(p)/GF(2^m) - offloads TLS 1.2 handshake and secure boot verification from CPU.

FAQ

What is the primary function of the SLWSTK6020A evaluation kit?

The SLWSTK6020A is a fully assembled, USB-powered evaluation kit for the EFR32BG1P332F256GM48-B0 SoC. It provides debug interfaces (J-Link), onboard sensors (temperature/humidity), RGB LED, push buttons, and antenna options to accelerate BLE firmware development, RF characterization, and Bluetooth SIG qualification testing. The SLWSTK6020A enables rapid prototyping of battery-operated devices without custom PCB spin.

Does the SLWSTK6020A support Bluetooth 5 features such as long range or high data rate?

No - the SLWSTK6020A is based on the EFR32BG1P332, which implements Bluetooth 4.2 (Smart/LE). It does not support Bluetooth 5 physical layer enhancements like coded PHY (long range) or 2 Mbit/s LE PHY (high data rate). For those features, Silicon Labs' EFR32BG22 or EFR32BG24 platforms are required. The SLWSTK6020A remains fully compliant with Bluetooth SIG v4.2 qualification requirements.

Can the SLWSTK6020A be used to develop proprietary 2.4 GHz protocols alongside Bluetooth?

Yes - the underlying EFR32BG1P332 SoC on the SLWSTK6020A supports both Bluetooth Smart and proprietary 2.4 GHz protocols (GFSK, 2/4-FSK, shaped OQPSK) via Simplicity Studio SDK. The radio is configurable down to register level, enabling custom PHY layers, packet formats, and modulation schemes. This dual-mode capability makes the SLWSTK6020A suitable for hybrid applications like BLE provisioning followed by proprietary sensor data streaming.

What debug and programming interfaces does the SLWSTK6020A provide?

The SLWSTK6020A integrates an onboard J-Link debugger supporting SWD interface, enabling full-speed debugging, flash programming, and real-time trace of the EFR32BG1P332 SoC. It also exposes UART (via USB CDC), I2C, SPI, and GPIO headers for peripheral bring-up. No external debugger is needed - firmware can be loaded and debugged directly through the micro-USB port using Simplicity Studio IDE.

Is the SLWSTK6020A RoHS-compliant and qualified for industrial temperature range?

Yes - the SLWSTK6020A uses the EFR32BG1P332F256GM48-B0 SoC, rated for -40 °C to +85 °C operation and manufactured under RoHS-compliant processes. All passive components, PCB, and connectors on the SLWSTK6020A board meet RoHS Directive 2011/65/EU. Full compliance documentation, including test reports and substance declarations, is available via Silicon Labs' product portal and Aetrix Electronics' quality portal.
