NXP targets high-speed data acquisition applications with new microcontroller

NXP Semiconductors has unveiled the LPC4370 microcontroller, described by the company as “a complete solution for high-speed data acquisition applications available on a single chip.” Powered by a 204-MHz ARM Cortex-M4 processor the device also features the fastest 12-bit ADC currently available on a Cortex-M microcontroller with a sampling rate of 80 Msps.

In addition, the LPC4370 has a 204-MHz Cortex-M0 co-processor for offloading control and I/O tasks like handling USB stacks, as well as a dedicated subsystem for handling programmable digital I/O and pre- or post-processing. Advanced peripherals include Hi-Speed USB with on-chip PHY and Ethernet for high-speed communications, and a graphics LCD controller for display interfacing.

Demanding data acquisition applications such as spectrum analysis, current measurement, digital signal processing, audio streaming / processing, and analytical instrumentation typically require multiple chips for input, processing and output. The LPC4370 looks to break new ground by integrating this functionality in a single chip, eliminating data bottlenecks, improving power efficiency and noise performance, as well as reducing the overall PCB footprint, cost and application complexity.

The multi-core architecture of the LPC4370 also offers simplified algorithm partitioning. With its large SRAM and flexible memory expansion, the LPC4370 allows system designers to tailor the memory type and size to their specific application requirements.

“Our new LPC4370 creates a single-chip solution for high-speed data acquisition applications,” said Ross Bannatyne, general manager, mass market microcontroller product line, NXP Semiconductors. “With an integrated 80-Msps 12-bit ADC, the LPC4370 provides a competitive edge in high-speed analogue data conversion and opens significant possibilities in streamlining data acquisition, processing and communications for a wide range of data-intensive applications.”

The LPC4370 is pin-compatible with all LPC4300 and LPC1800 series microcontrollers in similar packages. LPC-Link 2, the standalone debug adapter introduced by NXP in April 2013, is based on the LPC4370 microcontroller.
