Mouser is now stocking the Silicon Labs EZR32 32-bit wireless microcontroller families. They are the latest in the Silicon Labs offering of wireless microcontrollers, delivering a high-performance, low-energy wireless solution integrated from compact packages. The EZR32 microcontrollers feature an ARM Cortex-M4 or Cortex-M3 core combined with a sub-GHz RF transceiver, making them ideal for battery-powered applications including utility metering, fitness monitoring and home automation. The devices are available in three families: LG330 (M3 with USB), WG230 (M4 without USB), and WG330 (M4 with USB). Each family offers best-in-class RF performance with low active power consumption through Silicon Labs EZRadio or EZRadioPro transceivers, as well as support for precision peripherals that include a 12 bit analog-to-digital converter (ADC) and a 12-bit digital-to-analog converter (DAC). All microcontrollers in the EZR32 series feature up to 41 general purpose I/O (GPIO) pins that support up to 16 asynchronous external pin interrupts. The LG330 microcontrollers are based on an ARM Cortex-M3 processor running at up to 48MHz and include up to 256 kBytes of flash memory to provide high performance and high efficiency. Onboard USB 2.0, I2C with SMBus support, UART/SPI (USART), UART, and Low Energy UART (LEUART) offer flexible serial communication for a variety of applications. The WG230 and WG330 microcontrollers are based on an ARM Cortex-M4, which also includes a floating point unit both running at up to 48MHz and includes up to 256 kBytes of flash memory. Both the WG230 and WG330 families include I2C, USART, UART, and LEUART interfaces; and the WG330 families also include USB 2.0. Both families also offer models that feature EZRadio or EZRadioPro transceivers with power amplification up to 20dBm. The wireless microcontrollers are ideal for touch-based, battery-powered Internet of Things (IoT) and industrial applications that require long battery lifetimes and energy-efficient human interfaces. For a low-cost way to evaluate the performance and features of Silicon Labs wireless products, SLWSTK62xxx EZ Wireless Starter Kits are available. The kits provide the hardware and software tools to develop and debug applications using Silicon Labs low-energy radios. Hardware tools include an on-board debugger, advanced energy monitoring, and integrated packet trace.
