D52 ANT SoC Module Series


Dynastream Innovations is pleased to offer the D52 series of ANT SoC Modules, based on Nordic Semiconductor’s nRF52832 SoC supporting ANT, Bluetooth® low energy and extended features such as NFC.  This expands Dynastream’s portfolio of multi-protocol ultra-low power wireless modules, popularized with the N5 series of modules.  Features of the D52 series include:

  • Nordic Semiconductor’s nRF52832 chip, with 64kB RAM and 512kB Flash and a 32-bit ARM Cortex M4F CPU
  • Concurrent ANT and Bluetooth low energy protocol operation using supported SoftDevices (pre-compiled protocol stack solutions for the nRF52 SoCs):
    • S212 – ANT only SoftDevice from Dynastream Innovations
    • S332 – concurrent ANT and Bluetooth low energy SoftDevice from Dynastream Innovations
    • S132 – Bluetooth low energy only SoftDevice from Nordic Semiconductor
  • Signing and registering a Module Distribution Agreement with Dynastream waives royalty fees for the use of Dynastream SoftDevices on D52 series modules.  Click here for more information.
  • Certification of compliance with regulation standards in major markets including North America, Europe, Australia / New Zealand, Japan and Korea
    • In order to be able to re-use Dynastream regulatory certifications, D52 series modules must be loaded with an approved SoftDevice running BLE or ANT.  This can be acknowledged by registering a Module Distribution Agreement with Dynastream, which will also waive royalty fees for using Dynastream SoftDevices on D52 series modules.  Click here for more information.
  • Qualification by the Bluetooth SIG
  • Onboard 32MHz and 32.768kHz crystal clocks
  • Preloaded ANT Network Processor Application, which uses the S212 SoftDevice (scalable ANT protocol stack with 15 channel support).  The application provides a standard ANT serial interface front-end that can be connected to an external application controller.
  • Easy reprogramming via the onboard SWD interface pins using off-the-shelf ARM programming tools
  • Drop-in compatibility with Dynastream C7, AP2 and N5 M4 and M8 modules  (in certain configurations)
  • Multiple form factors including 20x20mm and 14x9.8x2.0mm modules
  • The D52 series development kit (D52DK1) contains everything necessary to evaluate and begin development with D52 series modules, with support for the Nordic nRF5 SDK.
