NXP Semiconductors LPC1700 Microcontrollers
NXP Semiconductors LPC1700 Microcontrollers are cost-effective, low-power Cortex-M3 MCUs featuring best-in-class peripheral support such as Ethernet, USB 2.0 Host/OTG/Device, and CAN 2.0B. Operating at speeds up to 120MHz, the LPC1700 MCUs have up to 512KB of FLASH, up to 64KB of SRAM, 12-bit A/D, and 10-bit D/A Converters as well as an internal RC oscillator. 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 LPC1700 series is offered in LQFP80, LQFP100, LQFP-144, LQFP-208, TFBGA-180, and TFBGA-208 packages, and are pin compatible with the LPC2300 series of ARM7 microcontrollers. This allows designers to compare the M3 and ARM7 cores in the same socket and simply choose the microcontroller that is best for their application.
