Application Specific SoC
ARM Cortex-M Audio SoC
ARM-based System-on-a-Chip solutions providing powerful and cost effective single-chip solutions for applications that require video or voice/audio features.
ARM Cortex-M Audio SoC group, based on the Cortex-M0 core, includes microprocessors designed for voice and audio applications which require audio recording and playback. This group consists of two series:
- AUI Enablers Series - voice devices for a record / playback of voice and audio signals in/from an internal Flash memory or an external SPI Flash. They can run up to 50 MHz and are equipped with 145 KB Flash memory, microphone preamplifier, 16-bit ADC, many interfaces, like UART, SPI, I2C and I2S and can realize 2/3/4/5-bit ADPCM and 8/16-bit PCM compression algorithms. They enable designers to develop complicated algorithms such as voice recognition or text to speech.
- NuVoice Series - voice processing devices with high integration analog and digital peripherals and high performance algorithms designed for varieties of voice applications. They can run up to 48 MHz and are equipped with up to 72 KB Flash memory, 12-bit ADC and many analog peripherals, like: 13-bit DAC, hardware mixer with PCM input, speaker amplifier (up to 550 mW) or volume control. They can be used in cost effective applications, like portable medical devices, voice activation/recognition for simple commands, high quality recorders, remote control, voice announcement systems, audio photo frames and albums and many others.
