Embedded Firmware and Hardware Development

Neutron Code is specializing in a field of high-performance hi-res audio processing on mobile platforms for more than 10 years.

Being the professionals in this field, acknowledged by many users of our end-user audio-dedicated applications, we offer the specialized firmware/hardware hi-res audio solution based on NXP K2x/K6x MCUs which can be used as a high-performance USB DAC or ADC.

Features

  • NXP MCU K26/K66
  • Asynchronous mode (USB Audio 2.0)
  • ES9038Q2M or ES9218P DAC (can be adopted to other audio DACs by request)
  • PCM: up to 384 kHz, 16, 24, 32-bit streams
  • Native DSD: up to DSD256
  • DoP (DSD64, DSD128)
  • Headset built-in microphone support (exposed as USB input stream: 16-bit, 8-48 kHz)
  • Headset jack detection
  • Indication on 96x16 OLED display (optional, SSD1306 microcontroller, can be adopted to any other display model and controller chip)
  • Efficient power management to minimize power impact on the host device
  • Bootloader mode (NXP Kinetis Bootloader)
  • Updates of firmware via the own specialized utility (Configurator, Windows/Linux/OSX) or via bootloader mode with KinetisFlashTool utility
  • Power-persistent device parameters configuration via Configurator utility
  • Compatible with Android, Apple, Windows 10 platforms without a need for an additional drivers
