120 MHz, 32-bit
Microcontrollers with
Cortex-M3™ core,
LPC1700 series
Cortex-M3 based microcontrollers with
Ethernet, USB, CAN and 12-bit ADC
The LPC1700 series of low power cost-effective Cortex-M3 microcontrollers feature bestin-class peripheral support such as Ethernet, USB 2.0 Host/OTG/Device, and CAN 2.0B.
Operating at speeds up to 120 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 120 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 available 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.
