LPC-4350-DB1 Evaluation Board Features

LPC43xx Series Device Features

The LPC43xx dual-core microcontroller features high speed USB (with on-chip PHY), a large internal SRAM, new innovative peripherals like the State Configurable Timer, the signal processing performance of ARM's Cortex-M4 core with Floating Point Unit and Cortex-M0 coprocessor.

LPC43xx key features:

• ARM Cortex-M4 - DSP (Digital Signal Processor) with Floating Point Unit, 204MHz, 32-bit.
• ARM Cortex-M0 - asymmetrical coprocessor, 204MHz, 32-bit
• Dual-bank flash memories up to 1MB (internal flash memory is not available at LPC4350 microcontroller).
• On-chip SRAM up to 264KB
• New innovative peripherals - SPI Flash Interface, State Configurable Timer (SCT), and Serial GPIO, etc.
• 2X High Speed USB - one (with on-chip High Speed PHY) is connected to the Mini USB connector at LPC4350-DB1 evaluation board
• Memory Protection Unit (MPU)

LPC4350-DB1 Development Board Components

The LPC4350-DB1 development board contains most of the extensively used components. Its peripheral support can be easily extended by the LPC4350-DB1 PCB soldering options and wide range of extension boards.

The LPC4350-DB1 evaluation board hardware components are:
