Features

RF Transceiver

  • Supports 290-340 MHz, 424-510 MHz, and 862-1020 MHz frequency bands
  • High sensitivity: down to -120 dBm at 1.2 kbps
  • High selectivity: 80 dB blocking immunity
  • Low current: Rx = 16 mA
  • Programmable output: -18 to +17 dBm in 1 dB steps
  • FSK bit rates up to 600 kbps
  • FSK, GFSK, MSK, GMSK and OOK modulations
  • Packet engine with CRC, AES-128 encryption and 66-byte FIFO
  • Built-in temperature sensor and low battery indicator

MCU

  • Ultra-low-power 32-bit Arm® Cortex®-M0+ core. 2x more CoreMark/mA than the closest8/16-bit architecture. Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, maintaining an 8-bit look and feel?
  • Multiple, flexible low-power modes including new compute mode which reduces dynamic power by placing peripherals in an asynchronous stop mode
  • I²C, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core

Memory

  • 128 KB flash with 64 byte flash cache
  • 16 KB RAM

Peripherals

  • 16-bit ADC with configurable resolution, sample time and conversion speed/power
  • High-speed comparator with internal 6-bit DAC
  • 12-bit DAC with DMA support

Interfaces

  • Capacitive touch sense interface supports external electrodes
  • GPIO with pin interrupt support, DMA request capability and other pin control options
  • One I²C with DMA support, up to 100Kbps and compatible with MBus V2 features
  • One LPUART and two UART with DMA support

Operating Voltage and Temperature Range

  • 1.8 to 3.6 V operating voltage with on-chip voltage regulators
  • Temperature range of -40° C to +85° C

Software

  • Radio Test Tool
    • Run on PC connected through USB
    • Allow fast evaluation of the radio performance in a lab environment without need for writing software
    • Analysis of TX spectrum (output power, harmonics)
    • Modulation scheme impact (GFSK, BT, Mod index) on spectrum
    • Help on matching network tuning
    • Analysis of RX Sensitivity performance (RSSI, LNA input impedance, OOK threshold, AFC)
  • SMAC (Simple Media Access Controller)
    • Simple communication and test apps based on drivers/PHY utilities available as source code.
    • Small footprint (<10 KB)
    • Supports point-to-point communication (bi-directional RF communication link), broadcast communication
