NXP introduces high-bandwidth microcontrollers

NXP Semiconductors has announced the LPC1700 series, a fast microcontroller range based on the ARM Cortex-M3 processor.

Running at speeds up to 100MHz, NXP said that the LPC1700 series of microcontrollers operates from 28 to 64 per cent faster than any competitive Cortex-M3 microcontroller.

This performance allows the LPC1700 series to operate high-bandwidth communications peripherals without bottlenecks.

The LPC1700, based on the new Cortex-M3 Revision 2 core, features tightly-integrated power control, including a Wake-up Interrupt Controller (WIC) that allows for efficient entry into and exit from lowest power sleep states.

It is pin-to-pin compatible with the ARM7-based NXP LPC2300 series.

This compatibility allows customers to evaluate both the Cortex-M3 and ARM7-based products in the same socket and to choose the right microcontrollers for each application.

The LPC1700 series targets a wide range of applications, including eMetering, lighting, industrial networking, alarm systems, white goods and motor control.

The NXP LPC1700 microcontroller series offers support for communication peripherals including 10/100 Ethernet, USB on-the-go/host/device and two CAN interfaces; all of which can operate simultaneously and without bus contention.

Other features include: a true 12-bit analogue-to-digital converter (ADC) and 10-bit digital-to-analogue converter (DAC); fast-mode plus (1Mb/s) IC bus; four UARTs; three SPI/SSP buses; an IS bus; a Memory Protection Unit (MPU); a Quadrature Encoder Interface; and Motor Control Pulse Width Modulator (PWM).

The NXP LPC1700 will be supported by the same tool vendors as NXP's ARM-based 32-bit MCUs.

Code Red Technologies will offer support for the LPC1700 in its Eclipse-based Red Suite software development platform.
