LPC1700 Series Cortex-M3 Microcontrollers

Cortex-M3 based microcontrollers with Ethernet, USB, CAN and 12-bit ADC now at Digi-Key

LPC1700 Series Cortex-M3™ MicrocontrollersNXP Semiconductor's LPC1700 series of low power cost-effective Cortex-M3 microcontrollers feature best-in-class peripheral support such as Ethernet, USB 2.0 host/OTG/Device, and CAN 2.0B. Operating at speeds up to 100 MHz, they have up to 512 KB of FLASH, up to 64 KB of SRAM, 12-bit A/D and 10-bit D/A converters as well as an internal RC oscillator.

The NXP LPC1700 series uses a low power, cost effective Cortex-M3 core that operates at up to 100 MHz. Each device has up to 512 KB of Flash and up to 64 KB of SRAM. The LPC1700 series features a multi-layer AHB bus that allows high-bandwidth peripherals such as Ethernet and USB to run simultaneously, without impacting performance.

The LPC176x devices are availabe in an LQFP100 package while the LPC175x MCUs are offered in an LQFP80 package. The LPC1700 series is pin compatible with the popular NXP LPC2300 series of ARM7 microcontrollers, allowing designers to compare the M3 and ARM7 cores in the same socket and simply choose the microcontroller that is best for their application. With its wide array of peripherals and high performance, the LPC1700 is ideal for e-Metering, lighting, industrial networking, alarm systems, white goods and motor control applications.
