 Product Description

Pulsed Coherent Radar (PCR) Module - XM112

Acconeer’s XM112 pulsed coherent radar module offers high precision distance measurement with mm accuracy and high update rate frequency. The pulsed coherent radar module XM112 from Acconeer is a 24 mm x 16 mm module that integrates the A111 pulsed coherent radar and a 32-bit ARM® Cortex®-M7 ATSAME70Q20A microprocessor on the same printed circuit board (PCB). The ATSAME70Q20A is equipped with 384 Kbytes SRAM and 1 MB Flash and has a maximum core processor frequency of 300 MHz. The XM112 is a reference module that can be integrated into a product via the slim 30-pin board-to-board connector to decrease users cost and time for bringing a product to market. The XM112 can also be used as an evaluation kit together with the breakout board XB112.


The XM112 is delivered with Acconeer RSS software including SDK (Software Development Kit) for stand-alone usage where customer can embed their own application on top of Acconeer RSS software. Acconeer RSS software provides API to set A111 sensor configuration and to retrieve supported radar services and detector data. The XM112 module can also be controlled by external host using register based protocol (UART, SPI and I2C). The module is suitable for applications in various market segments such as IoT, automotive, industrial, robots, drones, smart cities, healthcare, mobile and wearables, and power tools.



  • The A111 60 GHz Pulsed Coherent radar (PCR) with integrated baseband, RF front-end and Antenna in Package (AiP).
  • The Atmel ATSAME70Q20A microprocessor base on an ARM® Cortex® -M7, 32-bit, running at up to 300 MHz, 384 Kbytes SRAM and 1 Mb Flash.
  • Formfactor 24 x 16 mm
  • Single supply operating voltage 1.8V
  • Clock reference 24 MHz XTAL
  • Operating temperature -40° to 85°C
  • External interfaces SPI, UART, I2C
  • SWD for SW flash and debug
  • External interrupt support


The XM112 can be used for accurate distance ranging, movements and material detection:

  • High precision distance measurements with high update frequency
  • Measures absolute range up to 2m with an absolute accuracy in mm.
    • Note: 2m ranging is guaranteed for an object size, shape and dielectric properties corresponding to a spherical corner reflector of 5 cm radius.
  • Measures relative accuracy in µm
  • Possible to recognize movement for several objects
  • Support continuous and single sweep measurement mode


Easy integration:

  • Can be integrated behind plastic or glass without any need for a physical aperture
  • 1.8V single power supply, enable with Power on Reset (PoR)
