LPC4300 Series: High Performance Microcontrollers (MCUs) based on ARM® Cortex®-M4/M0 Cores

LPC4300 Series microcontrollers combine the high performance and flexibility of an asymmetric dual-core architecture (ARM Cortex-M4F and Cortex-M0 coprocessor) with multiple high-speed connectivity options, advanced timers, analog, and optional security features to secure code and data communications. DSP capabilities enable all LPC43xx families to support complex algorithms in data-intensive application. Flash and Flashless options support large, flexible internal and external memory configurations. Pin-and-software compatibility with LPC1800 Series MCUs enables LPC43xx MCUs to provide a seamless migration path for increasing processing power and adding the flexibilty of partitioning application tasks across cores.

The LPC4300 Series MCUs are ideal solutions for:

  • smart meters
  • embedded audio
  • industrial automation and control, telematics, white goods, electronic instruments, power management
  • point-of sale devices
  • medical and fitness devices, diagnostic equipment
  • secure connected gateways, secure communication hubs
  • automotive aftermarket, including telematics
  • data collectors and navigation
