• BelaSigna R262 Reference Design 1

The BelaSigna R262 Reference Design 1 (RD1) is a miniature, self-contained unit that can be integrated into a product or prototype to evaluate the performance of the BelaSigna R262 DSP from ON Semiconductor. The RD1-board has been designed with focus to minimize the cost for production, by using components and component classes with very short lead times.

Key Features
The Reference Design 1 has the following key features:
  • A miniature size of only 25 mm by 25 mm
  • The 26-ball WLCSP version of BelaSigna R262 (BR262W26A103E1G)
  • Two MEMS microphones spaced 10 mm apart (Knowles part number SPU0410HR5H-PB)
  • Through-hole test points for external connections
  • Configured to boot directly to the ROM application using the internal clock
  • I2C and GPIO signals available on test points
  • An onboard I2C EEPROM for optional custom application


In the package you will receive with this product is a link to a support web page that contains all information about the product including:

  • Schematic files in PDF format
  • Design files: Board and Schematic files for Altium Designer 17
  • Production files: Gerber files, NC Drill files, BOM, Pick and Place
  • Link to a software that can be used to customize the speech enhancement

Samples (NEW)

As a further step to support your design-in of the Belasigna R262 chip, you can request samples of the BR262W26A103E1G chip directly from us.
