NXP Semiconductors recently introduced the LPC1700 series microcontroller family. The LPC1700 is based on the ARM Cortex-M3 Revision 2 processor core. Running at speeds up to 100 MHz, the LPC1700 microcontrollers operates from 28-64% faster than any competitive Cortex-M3 microcontroller. This performance enables the LPC1700 series to operate the high-bandwidth communications peripherals such as Ethernet, USB On-The-Go/Host/Device, and CAN simultaneously without bottlenecks. The LPC1700 series is priced from $2.49 to $4.75 in 10ku volumes. Engineering samples will be available starting in December 2008.
The LPC1700 adds tightly integrated power control, including a unique Wake-up Interrupt Controller (WIC) that allows for graceful and efficient entry into and exit from lowest power sleep states. In addition, the LPC1700 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 their applications. The LPC1700 series is ideal for a wide range of applications, including eMetering, lighting, industrial networking, alarm systems, white goods, and motor control.
NXP LPC1700 Microcontroller Features
- 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
