LPC175x/176x - 100 MHz, 32-bit MCUs with Cortex-M3 Core

The 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 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.
