EZR32HG Wireless MCUs EZR32HG320 Data Sheet EZR32HG320 Wireless MCU family with ARM Cortex-M0+ CPU, KEY FEATURES USB, and sub-GHz Radio Silicon Labs energy efficient 32-bit The EZR32HG Wireless MCUs are the latest in Silicon Labs family of wireless MCUs Wireless MCUs delivering a high performance, low-energy wireless solution integrated into a small form Based on ARM Cortex M0 CPU core with factor package. By combining a high performance sub-GHz RF transceiver with an ener- 64 kB of flash and 8 kB RAM gy efficient 32-bit MCU, the EZR32HG family provides designers the ultimate in flexibility Best-in-class RF performance with EZradio with a family of pin-compatible devices that scale with 64/32 kB of flash and support Sili- and EZRadioPro transceivers con Labs EZRadio or EZRadioPRO transceivers. The ultra-low power operating modes Ultra-low power wireless MCU and fast wake-up times of the Silicon Labs energy friendly 32-bit MCUs, combined with Low transmit and receive currents the low transmit and receive power consumption of the sub-GHz radio, result in a solu- tion optimized for battery powered applications. Ultra-low power standby and sleep modes 32-Bit ARM Cortex wireless MCUs applications include the following: Fast wake-up time Alarm and security systems Rich set of peripherals including 12-bit Energy, gas, water and smart metering ADC and IDAC, multiple communication Building and home automation Health and fitness applications interfaces (USB, UART, SPI, I2C), multiple Consumer electronics GPIO and timers AES Accelerator with 128-bit keys EZR32HG320 F64/F32 Energy Management Core and Memory Clock Management Security Voltage Voltage Hardware Regulator Comparator AES ARM Cortex M0+ processor Brown-out Power-on Reset Detector Flash RAM Debug DMA Program Memory Interface Controller Memory w/ MTB 32-bit bus Peripheral Reflex System Transceiver Serial Interfaces I/O Ports Timers and Triggers Analog Interfaces ASK, OOK General TX 18 mA 142-1050 2 External Timer/ Real Time G(FSK) USART I C Purpose ADC +10 dBm MHz Interrupts Counter Counter 4(G)FSK I/O Low RX 10 mA Pin Pin Pulse Watchdog Current Preamble SPI SPI Energy 1 Mbps Reset Wakeup Counter Timer DAC Sense 6.0 mA USB Low Antenna 133 dBm Energy Diversity sensitivity UART silabs.com Building a more connected world.
