Product details

Overview

SLWSTK6202A 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 operation down to 0.65 µA in Stop Mode. It enables rapid prototyping of battery-powered smart metering, home automation, and sensor network applications.

For engineers reviewing the SLWSTK6202A datasheet, SLWSTK6202A pinout, SLWSTK6202A application, or SLWSTK6202A equivalent, this page delivers verified hardware configuration details, RF performance metrics, energy mode behavior, peripheral routing constraints, and direct comparison with compatible development platforms - all grounded in Silicon Labs' official documentation and Simplicity Studio reference design data.

Technical Context

The SLWSTK6202A implements the EZR32LG330F256R68G SoC in QFN64 package, featuring a 48 MHz ARM Cortex-M3 CPU, 256 kB flash/32 kB RAM, and an integrated +20 dBm EZRadioPRO transceiver with –133 dBm sensitivity. Its RF subsystem uses USART0 for SPI-based radio control, PRS for GPIO0/GPIO1 routing, and dedicated IRQ/SDN/nSEL pins for synchronous transceiver management.

Hardware-level low-energy operation is enforced via EM0–EM4 modes, with LEUART, LETIMER, and LESENSE active in EM2. The kit includes onboard J-Link debugger, USB-to-serial bridge, antenna switch, SMA RF connector, and configurable power domains supporting dual-supply (VDD/VBAT) operation for backup RTC and retention register use.

Key Specifications

Parameter	Value and Actual Design Meaning
Core	ARM Cortex-M3 @ up to 48 MHz - delivers deterministic real-time control with Memory Protection Unit and Wake-up Interrupt Controller for secure, low-latency wake-from-sleep.
Memory	256 kB flash / 32 kB RAM - supports full-stack wireless protocol stacks (e.g., IEEE 802.15.4g, WM-Bus) plus application logic without external memory.
RF Transceiver	EZRadioPRO with +20 dBm output & –133 dBm sensitivity - enables long-range, license-free sub-GHz communication in 142–1050 MHz bands with <69 dB adjacent-channel selectivity.
Low-Energy Modes	0.65 µA Stop Mode, 20 nA Shutoff Mode - extends battery life to years in periodic sensor-read-and-transmit applications (e.g., water/gas metering).
Peripherals	USB 2.0 Full-Speed OTG, 2× I²C, 3× USART, 2× UART, 2× LEUART, 12-bit ADC/DAC, AES-128/256 accelerator - enables secure, mixed-signal edge processing with minimal external components.
GPIO & Routing	38-pin GPIO with PRS-driven signal routing - allows dynamic assignment of radio GPIO0/GPIO1 to physical pins (e.g., PA0/PA1) without firmware recompile.

FAQ

What is the primary target application for the SLWSTK6202A?

The SLWSTK6202A is engineered for rapid validation and firmware development of sub-GHz wireless endpoints in utility metering (gas/water/electricity), home/building automation, and industrial sensor networks. Its integrated EZR32LG330F256R68G SoC provides certified RF performance, ultra-low-power sleep modes, and protocol-ready peripherals - enabling functional prototypes that map directly to production-grade SLWSTK6202A-based designs.

Does the SLWSTK6202A support over-the-air (OTA) firmware updates?

Yes, the SLWSTK6202A supports OTA firmware updates via its onboard USB interface and pre-programmed UART bootloader (AN0003). When configured with a host application using Simplicity Studio's Network Debugger, SLWSTK6202A can receive encrypted firmware images over its sub-GHz radio link and execute secure in-field updates using the integrated AES-128/256 accelerator and flash write protection features.

Can the SLWSTK6202A operate from a single-cell lithium battery?

Yes, the SLWSTK6202A operates across 1.98–3.8 V, fully supporting common 3.0–3.6 V single-cell Li-ion/Li-SOCl₂ batteries. Its 0.65 µA Stop Mode and 20 nA Shutoff Mode allow multi-year operation in duty-cycled sensor applications, while the integrated voltage comparator (VCMP) and BURTC enable precise low-battery detection and time-stamped shutdown logging without external circuitry.

How is RF calibration handled on the SLWSTK6202A?

The SLWSTK6202A leverages factory-programmed calibration data stored in the EZR32LG330's read-only information block, including HFRCO tuning, ADC offset/gain, and temperature sensor coefficients. During initialization, the device auto-loads these values - eliminating manual calibration steps. RF frequency accuracy is maintained via automatic frequency control (AFC) and crystal oscillator compensation routines built into the radio firmware stack.

Is the SLWSTK6202A pin-compatible with other Silicon Labs WSTK platforms?

No, the SLWSTK6202A is not pin-compatible with other Wireless Starter Kits (e.g., SLWSTK6101A or SLWSTK6220A) due to its unique QFN64 EZR32LG330 SoC footprint, dedicated RF layout, and custom debug/antenna switching circuitry. However, firmware developed on SLWSTK6202A is source-code portable to production EZR32LG330-based PCBs using the same peripheral mappings and Simplicity Studio SDK.
