Microchip SAM R30 System-in-Package (SiP)

Wireless microcontroller with 802.15.4 radio gives long battery life in connected lighting applications

Microchip has released the SAM R30, a System in Package (SiP) which combines an ultra-low power microcontroller with an IEEE 802.15.4 sub-1GHz radio to provide multi-year battery life in wirelessly connected smart devices. Its support for mesh networking makes it ideal for use in wide-area communications applications such as streetlight control.

The SAM R30 SiP is built using the SAM L21 MCU, which is based on a low-power Arm® Cortex®-M0+ core. The SiP features various ultra-low power sleep modes. For instance, it can run in sleep mode on a current of just 500nA and wake when triggered by serial communication or a General-Purpose Input/Output (GPIO) interrupt.

Operating at radio frequencies in a range from 769MHz to 935MHz, which offer longer range than 2.4GHz networks, the SAM R30 SiP gives developers the flexibility to implement a point-to-point, star or mesh network. Microchip helps developers get started immediately with Microchip’s free MiWi™ networking protocol stack.

Two nodes each equipped with the SAM R30 SiP can communicate over a span as long as 1km, giving a maximum range of 2km in a star topology. When used in a mesh network, the SAM R30 delivers reliable wide-area coverage for applications such as street lighting or wind and solar farms.

The SAM R30 SiP is available in two QFN packages:

  • The ATSAMR30E18 in a 5mm x 5mm QFN32 package
  • The ATSAMR30G18 in a 7mm x 7mm QFN48 package

SAM R30 Features

  • Memory provision:
    • 256kbytes of user-programmable Flash
    • 32kbytes of RAM
    • 8kbytes of low-power RAM
  • Up to four UART, SPI, and I2C interfaces
  • 12-bit, 350ksamples/s ADC

SAM R30 Applications

  • Security systems
  • Smart homes
  • Facility/building management
  • Municipal lighting
  • Consumer lighting
  • Industrial control
  • Metering
