ARM Cortex-M3 microcontrollers

NXP Semiconductors has introduced the LPC1700 series, a fast MCU (microcontroller) family. The operating speed up to 100MHz allows these MCUs to operate the high-bandwidth communications peripherals such as Ethernet, USB On-The-Go/Host/Device, and CAN simultaneously without bottlenecks. The LPC1700, based on the new Cortex-M3 Revision 2 core, adds tightly integrated power control, including a Wake-up Interrupt Controller (WIC) that allows for efficient entry into and exit from lowest power sleep states. The LPC1700 is pin-to-pin compatible with the ARM7-based NXP LPC2300 series. Other features of the MCUs include support for communication peripherals including 10/100 Ethernet, a true 12-bit analogue-to-digital converter (ADC) and 10-bit digital-to-analogue converter (DAC), Fast-Mode Plus (1 Mb/s) I²C bus - in addition to 4 UARTs, 3 SPI/SSP buses and an I²S bus, Real-Time Clock operating at less than 1uA, a Memory Protection Unit (MPU) allowing memory regions to be defined as read-only and protect them from corruption, and a Quadrature Encoder Interface and Motor Control Pulse Width Modulator (PWM) for flexible motor control.
