The NXP LPC177x and LPC178x series use a low-power, costeffective
Cortex-M3 core that operates at up to 120 MHz. Each
device has up to 512 KB of Flash and up to 96 KB of SRAM.
The LPC177x/LPC178x series features a multi-layer AHB bus
that allows high-bandwidth peripherals such as Ethernet and
USB to run simultaneously, without impacting performance.

The LPC177x/LPC178x devices are available in LQFP packages
with 144 or 208 pins and in TFBGA packages with 180 or
208 pins. LPC177x/LPC178x series are pin-compatible with
the popular NXP LPC2400 and LPC237x/8x series of ARM7
microcontrollers. This gives designers a simple way to compare
Cortex-M3 and ARM7 cores in the same socket, so they can choose the best device for their application.

The LPC1700 architecture, with its wide array of peripheral
and high performance, is ideal for displays, scanners, industrial
networking, alarm systems, medical diagnostics, and motor-control applications.
