The NDP120 is equipped with an Arm Cortex M0 Processor and a HiFi-3 DSP. The NDP120’s embedded Syntiant Core 2 supports more than 7 million parameters and can process multiple concurrent heterogeneous networks. 

Syntiant’s NDP120 enables low-power AI processing in all types of consumer tech products, including smartphones, earbuds, virtual assistants, laptops, home entertainment and security devices. The NDP120 also supports multi-sensor fusion, passive infrared detection, as well as accelerometer, gyroscope, magnetometer and pressure sensing applications. 

Key features of the NDP120: 

  • Syntiant Core 2 neural processor
  • Support for up to 7 audio streams
  • I2S/TDM output audio interface for streaming audio output, including post-processed audio
  • Embedded user-programmable HiFi-3 DSP
  • Deeply embedded Arm Cortex M0 microcontroller for device management with 48KB SRAM, dual-timers, and UART functionality
  • Stand-alone operation
  • Quad SPI target and controller interface
  • I2C serial interface for sensor applications and system interface
  • Up to 26 GPIO pins
  • Flexible clock generation
  • Onboard firmware decryption and authentication
  • 3.1 mm x 2.5 mm 42-ball WLBGA package (0.4 mm ball pitch)

The product has been presented the CES 2021 Innovation Awards for outstanding design and engineering in consumer technology products. 

“We are thrilled that our technology continues to be recognised by CTA in the embedded technologies category,” said Kurt Busch, CEO at Syntiant. “We believe our deep learning solutions will be the technology that bridges the gap between people and machines, and ultimately better connect people with people.”

The Syntiant NDP120 is sampling now and will be shipping in production volumes in summer 2021.
