NXP’s recent announced LPC4300 Digital Signal Controller at 204 MHz is the world’s fastest ARM® Cortex™-M4 processor and the industry’s first asymmetrical dual-core DSC with a Cortex-M0 co-processor. The LPC4300 is not just another Cortex-M4. It has proven to be a great match for customers that require high-performance microcontroller and DSP capabilities.

NXP also announced that it has increased the performance of its LPC1800 series to 180 MHz, extending its lead as the world’s fastest Cortex-M3-based microcontroller.

Designed in parallel, the LPC4300 and LPC1800 have been manufactured using the same ultra-low leakage 90-nm technology, are pin- and software-compatible, and share many key features.

The NXP LPC4300 is the fastest ARM Cortex-M4 microcontroller At 204 MHz available today. It is ideal for a wide range of applications like embedded audio, high-end motor control, industrial automation, point-of-sale, medical devices, and automotive accessories.

The LPC4300 has both a Cortex-M4 core and a Cortex-M0 core, the former one is optimized for real-time processing, and the latter optimized for real-time control. The small gate-count Cortex-M0 has been added to offload many of the control and I/O handling duties that drain the bandwidth of the Cortex-M4 core, allowing the Cortex-M4 to concentrate on what it does best: crunching numbers for digital signal control applications. Both cores are capable of running at 204 MHz.

There’s a State Configurable Timer sub-system inside, which lets designers configure advanced timing operations with state machine control including complex motor-control functions. Also with the Quad lane SPI flash interface, the LPC4300 extends the code and data memory map using inexpensive, low-pin count SPI data flash. Additionally, the LPC4300 has the Serial GPIO interface, which is capable of emulating standard interfaces such as multiple I2S for a 7.1 multi-channel audio connection.

NXP and its partners offer extensive software and development tool support for the LPC4300 and LPC1800, including a CMSIS-compliant peripheral driver library; a full-featured open-source USB library and USB ROM drivers supporting its Hi-Speed USB Host/Device/OTG interfaces with on-chip high-speed PHY; and the emWin graphic library from SEGGER free of charge for NXP customers. Dual-core debugging support is provided by leading ARM development tools including IAR Systems, Keil, and NXP’s Eclipse™-based LPCXpresso IDE.
