Cotex-M3 MCUs run at 100 MHz

18 March 2009 DSP, Micros & Memory

NXP Semiconductors recently developed the LPC1700 series, a high-speed microcontroller family based on the ARM Cortex-M3 processor. Running at speeds up to 100 MHz, the MCUs are suitable to operate their 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 unique wake-up interrupt controller (WIC) that allows for efficient entry into and exit from lowest power sleep states. Further, the MCUs are pin-to-pin compatible with the ARM7-based NXP LPC2300 series, allowing customers to evaluate both the Cortex-M3 and ARM7-based products in the same socket and to choose the right microcontrollers for their applications. The LPC1700 series targets a wide range of applications including eMetering, lighting, industrial networking, alarm systems, white goods and motor control.

The MCUs also boast features such as a true 12-bit analog-to-digital converter and 10-bit digital-to-analog converter, 1 Mbps I²C bus, four UARTs, three SPI/SSP buses and an I²S bus. They have a realtime clock operating at less than 1 μA and a memory protection unit (MPU) allowing memory regions to be defined as read-only and protect them from corruption. A quadrature encoder interface and motor control pulse width modulator allow for flexible, powerful motor control.
